In 2018,Dalton Transactions included an article by Reiners, Matthias; Maekawa, Miyuki; Baabe, Dirk; Zaretzke, Marc-Kevin; Schweyen, Peter; Daniliuc, Constantin G.; Freytag, Matthias; Raeder, Jan; Hohenberger, Johannes; Sutter, Joerg; Meyer, Karsten; Walter, Marc D.. Category: iodides-buliding-blocks. The article was titled 《Monomeric Fe(III) half-sandwich complexes [Cp’FeX2] – synthesis, properties and electronic structure》. The information in the text is summarized as follows:

The half-sandwich complex [Cp’Fe(μ-I)]2 (1; Cp’ = η5-1,2,4-(Me3C)3C5H2) is cleaved when heated in toluene to form a cation-anion pair [{Cp’Fe(η6-toluene)}+{Cp’FeI2}-] (2), in which the two Fe(II) atoms adopt different spin states, i.e., a low-spin (S = 0) and a high-spin (S = 2) configuration. Upon oxidation of 1 with C2H4I2, the thermally stable 15VE species [Cp’FeI2] (3) can be isolated, in which the Fe(III) atom adopts an intermediate spin (S = 3/2) configuration. Complex 3 is an excellent starting material for further functionalizations and it reacts with Mg(CH2SiMe3)2 to form the unprecedented Fe(III) (S = 3/2) bis(alkyl) complex [Cp’Fe(CH2SiMe3)2] (4). The resp. spin states of complexes 2-4 are confirmed by single-crystal x-ray crystallog., zero-field 57Fe Mossbauer spectroscopy, and solid-state magnetic susceptibility measurements. In contrast to the related 14VE high-spin (S = 2) Fe(II) alkyl species [Cp’FeCH(SiMe3)2], which resists the reaction with H2 as a consequence of a spin-induced reaction barrier, complex 4 reacts cleanly with H2 (8 bar) in cyclohexane to yield iron hydrides [{Cp’Fe}2(μ-H)3] (5) and [Cp’Fe(μ-H)2]2 (6) in a 1 : 4 ratio. However, when the hydrogenation of 4 is carried out in benzene, a green 19VE [Cp’Fe(η6-C6H6)] (A) intermediate is formed, which dimerizes to the bis(cyclohexadienyl)-bridged product [(Cp’Fe)2(μ2-η5:η5-C12H12)] (7). Further evidence for the intermediacy of [Cp’Fe(η6-C6H6)] (A) was gathered by X-band EPR and UV/vis spectroscopy. Interestingly, attempts to oxidize 7 with AgSbF6 proceeded via C-C bond cleavage instead of metal oxidation to form [Cp’Fe(C6H6)][SbF6] (8). After reading the article, we found that the author used 1,2-Diiodoethane(cas: 624-73-7Category: iodides-buliding-blocks)

1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Category: iodides-buliding-blocks

COA of Formula: C24H20I2O4 And the article was included in Inorganic Chemistry on April 2 ,2018. The article conveys some information:

Upon treatment with ZnII ions, a series of BINOL-bridged bis(phenanthroline) ligands was self-assembled into [M2L3] metallocages, which were carefully characterized by NMR spectroscopy and ESI-MS spectrometry. Among them, a racemic mixture of the BINOL-bridged bis(phenanthrolines) underwent chiral self-sorting to afford two homochiral metallocages. The narcissistic self-sorting process of the metallocages was observed in the complexation reaction of the constitutionally isomeric bis(phenanthrolines) with varying connection positions. Moreover, the endo hydroxyl-functionalized metallocage [Zn2{(S)-L2OH}3] exhibited catalytic activity and substrate selectivity for the Knoevenagel condensation reactions of aromatic tricarbaldehydes with malononitrile. The results came from multiple reactions, including the reaction of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3COA of Formula: C24H20I2O4)

《A proficient microwave synthesis with structure elucidation and the exploitation of the biological behavior of the newly halogenated 3-amino-1H-benzo[f]chromene molecules, targeting dual inhibition of topoisomerase II and microtubules》 was published in Bioorganic Chemistry in 2020. These research results belong to Fouda, Ahmed M.; Okasha, Rawda M.; Alblewi, Fawzia F.; Mora, Ahmed; Afifi, Tarek H.; El-Agrody, Ahmed M.. COA of Formula: C7H5IO The article mentions the following:

A series of β-enamionitriles, linked to the 8-bromo-1H-benzo[f]chromene moieties I (Ar = 2-ClC6H4, 4-IC6H4, 2,6-F2C6H3, etc.), was designed and synthesized under microwave irradiation conditions. Furthermore, the antiproliferative properties were evaluated against the human cancer cell lines MCF-7, HCT-116, and HepG-2 in comparison to the pos. controls Vinblastine and Doxorubicin, employing the viability assay. The obtained results confirmed that most of the tested mols. revealed strong and selective cytotoxic activities against the three cancer cell lines. The most potent cytotoxic compounds I (Ar = 2-ClC6H4, 4-ClC6H4, 4-BrC6H4, 2,3-Cl2C6H3, 2,5-Cl2C6H3) were elected for further examination, such as cell cycle anal., apoptosis assay, Caspase production, and DNA fragmentation. This study also revealed that the desired compounds stimulate cell cycle arrest at the G2/M phases, increase the production of Caspases 3, 8, and 9, and finally cause intrinsic and extrinsic apoptotic cell death. Moreover, these compounds suppress the action of topoisomerase II enzyme and also disrupt the microtubule functions. The SAR study of the synthesized compounds verified that the substitution on the Ph ring of the 1H-benzo[f]chromene nucleus, accompanied with the presence of the bromine atom at the 8-position, increases the ability of these mols. against different cell lines.

Battery-supercapacitor hybrid device (BSH) consisted of a battery-type electrode and a capacitor-type electrode is a promising candidate for both high energy and power d. energy storage systems. In an effort to design a high-performance battery-type electrode of BSH, we propose a facile and artful two-step strategy to obtain NiCo2S4 ultrathin nanosheets by utilizing bimetallic Co/Ni-ZIFs as a precursor. NiCo2S4 nanosheets are directly grown on nickel foam via this method, which involves the growth of Co/Ni-ZIFs and the morphol. of Co-Ni-S/NF transforms into ultrathin nanosheets through a simple sulfuration procedure. The as-prepared Co1Ni1-S/NF electrode achieves a high specific capacity of 301.1 mAh g-1 at 2 A g-1, which benefits from the synergistic interplay between Co and Ni ions and the unique 3D nanoarchitectures constructed by 2D ultrathin nanosheets. Moreover, Co1Ni1-S/NF and activated carbon/NF are chosen for fabricating a battery-supercapacitor hybrid device. The assembled Co1Ni1-S/NF//AC/NF BSH exhibits a large energy d. of 48.65 W h kg-1 at a power d. of 8.51 kW kg-1, a specific capacity of 80.56 mAh g-1 at 1 A g-1 and a remarkable stability over 5000 cycles at 5 A g-1.
