Pyridyl-Supported Pyrazolyl-N-Heterocyclic Carbene Ligands and the Catalytic Activity of Their Palladium Complexes in Suzuki-Miyaura Reactions was written by Zeng, Fanlong;Yu, Zhengkun. And the article was included in Journal of Organic Chemistry in 2006.Application of 877264-43-2 This article mentions the following:

Palladium complexes I (R¹ = H, Me; R² = n-Bu, n-C₇H₁₅; X = BF₄, PF₆) and II (R³ = 2,4,6-Me₃C₆H₂) of two new types of unsym. pyridyl-supported pyrazolyl-N-heterocyclic carbene ligands were synthesized and structurally characterized. A strategy to release the steric strain of the ligand was realized by the introduction of methylene linkers to the ligand mol. All the palladium complexes exhibited good to excellent catalytic activity in Suzuki-Miyaura reactions of Ph or p-tolylboronic acid with aryl halides including iodobenzene, aryl bromides, and activated aryl chlorides under mild conditions, revealing that the new ligands are promising for the construction of highly active transition-metal catalysts. In the experiment, the researchers used many compounds, for example, (5-Fluoro-2-iodophenyl)methanol (cas: 877264-43-2Application of 877264-43-2).

(5-Fluoro-2-iodophenyl)methanol (cas: 877264-43-2) belongs to iodide derivatives. Iodide-containing intermediates are common in organic synthesis, because of the easy formation and cleavage of the C–I bond. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Application of 877264-43-2

C(sp³)-H Bond Arylation and Amidation of Si-Bound Methyl Group via Directing Group Strategy was written by Han, Jie-Lian;Qin, Ying;Zhao, Dongbing. And the article was included in ACS Catalysis in 2019.Product Details of 5460-32-2 This article mentions the following:

Silylmethyl functionalization provides a general and efficient access to diverse organosilanes. The traditional methods for silylmethyl functionalization often involved silylmethylmetals or silylmethyl halides. In recent years, a C-H activation strategy has become one of the most attractive alternatives in organic synthesis. Authors envisioned that the attachment of a coordinating group at silicon of methylsilanes provides the opportunity to modify the silylmethyl group via directed C-H bond functionalization. However, despite employment of silicon tethers bearing a directing group (DG) for C(sp²)-H functionalization has been well established due to the fact that the silicon tethers are easily installable and removable/modifiable, applying this concept toward C(sp³)-H functionalization remains underdeveloped. Herein, authors successfully developed Ir^III/Rh^III-catalyzed C-H bond arylation/amidation of silyl Me group by using directing group strategy, which constitutes the most powerful access to benzylsilanes and amino-substituted silanes. Moreover, they demonstrated that the pyridine directing group on silicon atom can be easily removed, and the starting materials can also be efficiently recovered, which are different from those of pyridine-directed C-H functionalization of C-bound Me group. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Product Details of 5460-32-2).

4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.Product Details of 5460-32-2

Efficient zincation and magnesiation of chlorinated pyrimidines can be performed at convenient temperatures (e.g., 25 and 55°C) by using TMPMgCl·LiCl and TMP₂Zn·2MgCl₂·2LiCl (TMP = 2,2,6,6-tetramethylpiperidyl) as effective bases. Quenching of the resulting zincated or magnesiated pyrimidines with various electrophiles furnishes highly functionalized pyrimidines in 51-93 % yield. Oxidative aminations were carried out, thus leading to aminated pyrimidines. By using this methodol., we have also prepared pharmaceutically relevant pyrazolopyrimidines and the fungicide Mepanipyrim.

A dual light-driven palladium catalyst: Breaking the barriers in carbonylation reactions was written by Torres, Gerardo M.;Liu, Yi;Arndtsen, Bruce A.. And the article was included in Science (Washington, DC, United States) in 2020.Application In Synthesis of 1-Chloro-4-iodobutane This article mentions the following:

Transition metal-catalyzed coupling reactions have become one of the most important tools in modern synthesis. However, an inherent limitation to these reactions is the need to balance operations, because the factors that favor bond cleavage via oxidative addition ultimately inhibit bond formation via reductive elimination. Here, we describe an alternative strategy that exploits simple visible-light excitation of palladium to drive both oxidative addition and reductive elimination with low barriers. Palladium-catalyzed carbonylations can thereby proceed under ambient conditions, with challenging aryl or alkyl halides and difficult nucleophiles, and generate valuable carbonyl derivatives such as acid chlorides, esters, amides, or ketones in a now-versatile fashion. Mechanistic studies suggest that concurrent excitation of palladium(0) and palladium(II) intermediates is responsible for this activity. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Application In Synthesis of 1-Chloro-4-iodobutane).

1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Application In Synthesis of 1-Chloro-4-iodobutane

And the article was included in Asian Journal of Organic Chemistry in 2017.Recommanded Product: N,N-Diethyl-4-iodobenzamide This article mentions the following:

A general and efficient protocol for the synthesis of ortho-halogenated tertiary benzamides under mild conditions was described. Benzamides with various functional groups underwent ortho-iodination, bromination or chlorination with NXS using a cationic palladium catalyst generated in-situ from Pd(OAc)₂ and TfOH in DME. Given the generality, efficiency, mild conditions and readily available catalyst and halogenation reagents, this method provided a practical approach for the synthesis of ortho-halogenated benzamides. In the experiment, the researchers used many compounds, for example, N,N-Diethyl-4-iodobenzamide (cas: 77350-52-8Recommanded Product: N,N-Diethyl-4-iodobenzamide).

N,N-Diethyl-4-iodobenzamide (cas: 77350-52-8) belongs to iodide derivatives. Organic iodides are organic compounds containing a carbon-iodine (C-I) bond. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Recommanded Product: N,N-Diethyl-4-iodobenzamide

Recently, a natural compound leoligin, a furan-type lignan, was discovered as an interesting hit compound with an anti-inflammatory pharmacol. activity profile. We developed a modular and stereoselective approach for the synthesis of the edelweiss-derived lignan leoligin and used the synthetic route to rapidly prepare leoligin analogs even on the gram scale. Proof of concept of this approach together with cell-based bio-assays gained structural analogs with increased selectivity towards vascular smooth muscle vs. endothelial cell proliferation inhibition, a major benefit in fighting vascular neointima formation. In addition, we identified the structural features of leoligin analogs that define their ability to inhibit the pro-inflammatory NF-κB pathway. Results are discussed in the context of structural modification of these novel synthetic lignans.

Organic iodine compounds in fine particulate matter from a continental urban region: Insights into secondary formation in the atmosphere was written by Shi, Xiaodi;Qiu, Xinghua;Chen, Qi;Chen, Shiyi;Hu, Min;Rudich, Yinon;Zhu, Tong. And the article was included in Environmental Science & Technology in 2021.Related Products of 5460-32-2 This article mentions the following:

Atm. iodine chem. can significantly affect the atm. oxidation capacity in certain regions. In such processes, particle-phase organic iodine compounds (OICs) are key reservoir species in their loss processes. However, their presence and formation mechanism remain unclear, especially in continental regions. Using gas chromatog. and time-of-flight mass spectrometry coupled with both electron capture neg. ionization and electron impact sources, this study systematically identified unknown OICs in 2-yr samples of ambient fine particulate matter (PM_2.5) collected in Beijing, an inland city. We determined the mol. structure of 37 unknown OICs, among which six species were confirmed by reference standards The higher concentrations for ∑₃₇OICs (median: 280 pg m^-3; range: 49.0-770 pg m^-3) measured in the heating season indicate intensive coal combustion sources of atm. iodine. 1-Iodo-2-naphthol and 4-iodoresorcinol are the most abundant species mainly from primary combustion emission and secondary formation, resp. The detection of 2- and 4-iodoresorcinols, but not of iodine-substituted catechol/hydroquinone or 5-iodoresorcinol, suggests that they are formed via the electrophilic substitution of resorcinol by hypoiodous acid, a product of the reaction of iodine with ozone. This study reports isomeric information on OICs in continental urban PM_2.5 and provides valuable evidence on the formation mechanism of OICs in ambient particles.

β-Lactams with antiproliferative and antiapoptotic activity in breast and chemoresistant colon cancer cells was written by Malebari, Azizah M.;Fayne, Darren;Nathwani, Seema M.;O’Connell, Fiona;Noorani, Sara;Twamley, Brendan;O’Boyle, Niamh M.;O’Sullivan, Jacintha;Zisterer, Daniela M.;Meegan, Mary J.. And the article was included in European Journal of Medicinal Chemistry in 2020.Electric Literature of C8H7IO2 This article mentions the following:

A series of novel 1,4-diaryl-2-azetidinone analogs of combretastatin A-4 (CA-4) have been designed, synthesized and evaluated in vitro for antiproliferative activity, antiapoptotic activity and inhibition of tubulin polymerization Glucuronidation of CA-4 by uridine 5-diphosphoglucuronosyl transferase enzymes (UGTs) has been identified as a mechanism of resistance in cancer cells. Potential sites of ring B glucuronate conjugation are removed by replacing the B ring meta-hydroxy substituent of selected series of β-lactams with alternative substituents e.g., F, Cl, Br, I, and Me. The 3-phenyl-β-lactam I (R¹ = Ph) and 3-hydroxy-β-lactam I (R¹ = OH) (II) demonstrate improved activity over CA-4 in CA-4 resistant HT-29 colon cancer cells (IC₅₀ = 9 nM and 3 nM, resp., compared with IC₅₀ = 4.16μM for CA-4), while retaining potency in MCF-7 breast cancer cells (IC₅₀ = 17 nM and 22 nM, resp., compared with IC₅₀ = for 4 nM for CA-4). Compound II binds at the colchicine site of tubulin, and strongly inhibits tubulin assembly at micromolar concentrations comparable to CA-4. In addition, compound II induced mitotic arrest at low concentration in both cell lines MCF-7 and HT-29 together with down-regulation of expression of antiapoptotic proteins Mcl-1, Bcl-2 and survivin in MCF-7 cells. These novel antiproliferative and antiapoptotic β-lactams are potentially useful scaffolds in the development of tubulin-targeting agents for the treatment of breast cancers and chemoresistant colon cancers.
