A review. Soaring demand for technol. metals (e.g., Cd, Ni) and its ever-depleting primary resources ask for alternative recovery from secondary sources. Ni-Cd battery is one such source that can abridge the gap between demand and supply of such metals. Biogenic recovery, being environmentally benign, is explored for Cd and Ni recovery to manage the menace of spent Ni-Cd battery. Studies with 20, 40 and 60 mg/L Cd2+ initial concentrations in batch mode (in triplicates) at pH 7.0 ± 0.2, 30 ± 0.5°C and 120 rpm were conducted using sulfate-reducing bacteria for 10 days. Anal. of extracellular polymeric substance revealed that protein secretion was enhanced, thereby forming Cd-EPS binding. Biosolids were collected and freeze-dried for morphol. anal. viz. FESEM/EDX, PXRD and TEM, which revealed the formation of CdS nanoparticles (JCPDS card #00-042-1411) in range of 2-6 nm. Similarly, combined effect with 5, 10 and 20 mg/L Ni2+ at 20 mg/L Cd2+ were also investigated. Furthermore, to test the efficacy for real field application, spent Ni-Cd battery was dismantled and its powder was characterized, digested with concentrated HCl at 70°C and was fed in batch mode after cooling, wherein nanoparticles of Ni and Cd sulfides were formed that has potential as semi-conducting material. In addition to this study using 1-Iodopyrrolidine-2,5-dione, there are many other studies that have used 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Synthetic Route of C4H4INO2) was used in this study.

1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid. It acts as a source for I+ and involved in Hunsdiecker reactions for the conversion of cinnamic acids, and propiolic acids to the corresponding alfa-halostyrenes and 1-halo-1-alkynes respectively.

《Highly Emissive Perylene Diimide-Based Metallacages and Their Host-Guest Chemistry for Information Encryption》 was written by Hou, Yali; Zhang, Zeyuan; Lu, Shuai; Yuan, Jun; Zhu, Qiangyu; Chen, Wei-Peng; Ling, Sanliang; Li, Xiaopeng; Zheng, Yan-Zhen; Zhu, Kelong; Zhang, Mingming. Computed Properties of C5H4IN And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

Here we report two highly emissive perylene diimide (PDI)-based metallacages and explore their complexation with polycyclic aromatic hydrocarbons, such as pyrene, triphenylene, and perylene. The fluorescence quantum yields of metallacages exceed 90% and their binding constants with perylene can reach as high as 2.41 x 104 M-1 in acetonitrile. These features enable further tuning of the emission of the host-guest complexes to obtain white-light emission based on the complementary orange emission of the metallacages and the blue emission of perylene. Moreover, owing to the huge differences of their quantum yields in solution and in the solid state, the host-guest complexes are successfully employed for information encryption. This study offers a general approach for the construction of emissive metallacages and explores their application for information encryption. In the part of experimental materials, we found many familiar compounds, such as 4-Iodopyridine(cas: 15854-87-2Computed Properties of C5H4IN)

4-Iodopyridine(cas: 15854-87-2) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Computed Properties of C5H4IN

《Pd(II)-Catalyzed Enantioselective γ-C(sp3)-H Functionalizations of Free Cyclopropylmethylamines》 was written by Zhuang, Zhe; Yu, Jin-Quan. Formula: C7H7I And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

Herein, the Pd-catalyzed enantioselective C(sp3)-H functionalization of free aliphatic amines (cyclopropylmethylamines) enabled by a chiral bidentate thioether ligand was reported. This ligand’s privileged bidentate coordination mode and thioether motif favor the generation of the requisite mono(amine)-Pd(II) intermediate, thus enabling the enantioselective C-H activation of free amines. The resulting C-Pd(II) species could engage in either Pd(II)/Pd(IV) or Pd(II)/Pd(0) catalytic cycles, enabling access to a diverse range of products I [R1 = n-pentyl, 2,6-di-FC6H3, Bn, etc.; R2 = H, Boc, Bz; Ar = Ph, 4-MeC6H4, 4-pyridyl, etc.], II [R1 = H, Bn; R2 = H, 2,6,-di-FC6H3, 2,6,-di-ClC6H3, 2,6,-di-MeC6H3, (CH2)3C6H5] and III [R1 = H, CH2CH2CH(Me)2; R2 = Boc, 2,6,-di-FC6H3, 2,6,-di-ClC6H3, 2,6,-di-MeC6H3] through (hetero)arylation, carbonylation and olefination reactions. Consequently, this versatile reactivity offered medicinal chemists a general strategy to rapidly prepare and functionalize biol. relevant amines. In the experiment, the researchers used 1-Iodo-4-methylbenzene(cas: 624-31-7Formula: C7H7I)

N. Murthy; Saketi, Jagan Mohana Rao; Mutchu, Baby Ramana; Bollikolla, Hari Babu; Adil, Syed Farooq; Khan, Mujeeb. Recommanded Product: 625-99-0 And the article was included in Arabian Journal of Chemistry in 2020. The article conveys some information:

Copper-catalyzed novel, facile and efficient methods for the synthesis of various 2-aminobenzoxazoles and 2,5-diphenyltetrazoleamines was demonstrated. The reaction procedures were simple, with excellent substrate tolerance in good to high yields thus paving an excellent and useful way to establish a library of potentially active drug mols. This methodol. represents the first concept of copper-catalyst promoted domino C-N cross-coupling reaction towards the construction of 2-aminobenzoxazoles. In addition, the synthesis of 2,5-diaryltetrazoleamines using copper via inter mol. C-N cross-coupling reaction with aryl iodides was also reported. The proposed reaction mechanism involves copper based desulfurization/nucleophilic substitution and subsequent C-N cross-coupling reactions. Numerous applications of this methodol. was established for synthesizing diverse heterocyclic derivatives i.e. both electron rich and electron deficient systems. The experimental part of the paper was very detailed, including the reaction process of 1-Chloro-3-iodobenzene(cas: 625-99-0Recommanded Product: 625-99-0)

1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Recommanded Product: 625-99-0

《Discovery of novel liver X receptor inverse agonists as lipogenesis inhibitors》 was written by Chen, Ziyang; Chen, Hao; Zhang, Zizhen; Ding, Peng; Yan, Xin; Li, Yanwen; Zhang, Songxuan; Gu, Qiong; Zhou, Huihao; Xu, Jun. Category: iodides-buliding-blocks And the article was included in European Journal of Medicinal Chemistry in 2020. The article conveys some information:

Based on the co-crystal structures of LXRβ and its agonists (spiro [pyrrolidine-3,3′-oxindole] derivatives) discovered by us previously, we designed and synthesized a compound library to explore the agonistic activities. The library was screened with luciferase reporter assays, interestingly, it resulted in the discovery of 10 LXR inverse agonists besides 5 LXR agonists. To clarify the mechanism of the actions, we conducted mol. dynamics (MD) simulations on the LXR and inverse agonists complexes, and revealed that H3, H11 and H12 configurations are the key to turn on agonism or inverse agonism status for LXR. Binding tightly with H3, pushing H11 out and destabilizing H12 could form a bigger hydrophobic groove to accommodate NCOR1 to turn on LXR inverse agonism. The inverse agonist 10rr was further studied, and found as a lipogenesis inhibitor through down-regulating LXR target genes SREBP-1c, ACC, FAS and SCD-1, and demonstrated lipid-lowering effects in 3T3-L1 cells, HepG2 cells and mice with Triton WR-1339-induced hyperlipidemia. Therefore, we have proved that LXR inverse agonists can be promising agents for hyperlipidemia treatment. The experimental part of the paper was very detailed, including the reaction process of 1-Chloro-3-iodobenzene(cas: 625-99-0Category: iodides-buliding-blocks)

1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom.

《Low-Dimensional Hybrid Indium/Antimony Halide Perovskites: Supramolecular Assembly and Electronic Properties》 was written by Nicholas, Aaron D.; Halli, Ryan N.; Garman, Leah C.; Cahill, Christopher L.. HPLC of Formula: 15854-87-2 And the article was included in Journal of Physical Chemistry C in 2020. The article conveys some information:

The phenomenon of quantum confinement in hybrid low-dimensional lead-free perovskite derivatives continues to hinder the development of these materials for electron carrier devices such as next-generation solar cells. Spatial separation of metal-halide octahedra within crystal structures yields materials with greater moisture and photodegradation resistance, but at the expense of desired photophys. properties such as small band gaps. We report the synthesis and characterization of an unexplored isomorphic series of perovskite derivatives consisting of isolated dimeric metal-halide M2X104- (M = In, Sb; X = Cl, Br) anions charge-balanced with halopyridinium cations. Assembly of these species results in a supramol. network via extensive noncovalent interactions and may be described as a pseudo-zero-dimensional arrangement. Despite the low dimensionality, these materials display semiconductive optical band-gap energies owing to the appearance of an intermediate band due to hybridization of metal-halide at. and MOs. Low-temperature luminescence measurements provide evidence of electron delocalization where photoexcited metal/halide electrons are captured by organic cations via energetically accessible π* MOs, separating electron/hole pairs. Natural bonding orbital (NBO) calculations reveal that metal hybridization is more pronounced in compounds containing Sb3+ and can be influenced by noncovalent interactions between anionic and cationic building units.4-Iodopyridine(cas: 15854-87-2HPLC of Formula: 15854-87-2) was used in this study.

《Experimental and computational evidence on gold-catalyzed regioselective hydration of phthalimido-protected propargylamines: an entry to β-amino ketones》 was written by Marsicano, Vincenzo; Arcadi, Antonio; Aschi, Massimiliano; Michelet, Veronique. Safety of 1-Bromo-3-iodobenzene And the article was included in Organic & Biomolecular Chemistry in 2020. The article conveys some information:

The results of investigations on the Au-catalyzed regioselective hydration reaction of both alkyl- and aryl-substituted N-propargyl phthalimides I (R = CH3, C6H5, 2-thienyl, etc.) directed to the selective formation of the corresponding β-phthalimido ketones II are described. Exptl. data, in particular the observed regioselectivity, have been qual. supported by quantum-chem. calculations carried out on model systems in the framework of D. Functional Theory (DFT) followed by quantum theory of atoms in mols. (QTAIMS). The results suggest that the electronic features of the initial adduct between the propargyl triple bond and the Au(I) catalyst, in particular the character of the gold-triple bond interaction, are essential for the observed regioselectivity. Other effects, such as the presence of the solvent and the formation of a H-bond between the water mol. and the phthalimido moiety, although apparently irrelevant for the regioselectivity, have proven to be kinetically and catalytically rather important.1-Bromo-3-iodobenzene(cas: 591-18-4Safety of 1-Bromo-3-iodobenzene) was used in this study.

Martin, M. Trinidad; Marin, Mario; Maya, Celia; Prieto, Auxiliadora; Nicasio, M. Carmen published their research in Chemistry – A European Journal in 2021. The article was titled 《Ni(II) Precatalysts Enable Thioetherification of (Hetero)Aryl Halides and Tosylates and Tandem C-S/C-N Couplings》.Category: iodides-buliding-blocks The article contains the following contents:

Ni-catalyzed C-S cross-coupling reactions have received less attention compared with other C-heteroatom couplings. Most reported examples comprise the thioetherification of most reactive aryl iodides with aromatic thiols. The use of C-O electrophiles in this context is almost uncharted. Here, the authors describe that preformed Ni(II) precatalysts of the type NiCl(allyl)(PMe2Ar’) (Ar’=terphenyl group) efficiently couple a wide range of (hetero)aryl halides, including challenging aryl chlorides, with a variety of aromatic and aliphatic thiols. Aryl and alkenyl tosylates are also well tolerated, demonstrating, for the first time, to be competent electrophilic partners in Ni-catalyzed C-S bond formation. The chemoselective functionalization of the C-I bond in the presence of a C-Cl bond allows for designing site-selective tandem C-S/C-N couplings. The formation of the two C-heteroatom bonds takes place in a single operation and represents a rare example of dual electrophile/nucleophile chemoselective process.4-Iodopyridine(cas: 15854-87-2Category: iodides-buliding-blocks) was used in this study.

4-Iodopyridine(cas: 15854-87-2) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.Category: iodides-buliding-blocks
