The article was titled 《Engaging 1,7-diynes in a photocatalytic Kharasch-type addition/1,5-(SN”)-substitution cascade toward β-gem-dihalovinyl carbonyls》, and you may find the article in Chemical Communications (Cambridge, United Kingdom).COA of Formula: C6H4ClI The information in the text is summarized as follows:

A new and general photocatalytic Kharasch-type addition/1,5-(SN”)-substitution cascade of 1,7-diynes with alkyl halides such as BrCCl3 and CBr4 was reported for the first time, and used to produce 65 hitherto unreported β-gem-dihalovinyl ketones/aldehydes with moderate to excellent yields in a highly regioselective manner. This reaction tolerates a wide scope of substrates, which offers a green and efficient entry to fabricate synthetically important β-gem-dihalovinyl carbonyl scaffolds. Notably, the late-stage application of these resulting β-gem-dihalovinyl carbonyls shows high and unique reactivity profiles and demonstrates the versatility of their derivatization. Thus, e.g., treatment of diyne I with CBrCl3 under blue irradiation in presence of fac-Ir(ppy)3 and NaOAc base in EtOH afforded II (80%). In the experiment, the researchers used many compounds, for example, 1-Chloro-3-iodobenzene(cas: 625-99-0COA of Formula: C6H4ClI)

In 2022,Bouzriba, Chahrazed; Chavez Alvarez, Atziri Corin; Gagne-Boulet, Mathieu; Ouellette, Vincent; Lacroix, Jacques; Cote, Marie-France; C.-Gaudreault, Rene; Fortin, Sebastien published an article in European Journal of Medicinal Chemistry. The title of the article was 《Branched alkyl of phenyl 4-(2-oxo-3-alkylimidazolidin-1-yl)benzenesulfonates as unique cytochrome P450 1A1-activated antimitotic prodrugs: Biological evaluation and mechanism of bioactivation》.Safety of 3-Iodophenol The author mentioned the following in the article:

We recently discovered a new family of prodrugs deriving from Ph 4-(2-oxo-3-imidazolidin-1-yl)benzenesulfonates (PIB-SOs) bioactivatable by cytochrome P 450 1A1 (CYP1A1) into potent antimitotics referred to as Ph 4-(2-oxo-3-alkylimidazolidin-1-yl)benzenesulfonates (PAIB-SOs). PAIB-SOs display significant selectivity toward human breast cancer cells based on the N-dealkylation of PAIB-SOs into their corresponding PIB-SOs by CYP1A1. In this study, we have evaluated the mol. mechanism of the bioactivation of PAIB-SOs into PIB-SOs by branching the linear alkyl chain on the imidazolidin-2-one (IMZ) moiety of PAIB-SOs by branched alkyl groups such as iso-Pr, iso-Bu and sec-Bu. Our results show that PAIB-SOs bearing an iso-Bu group on the IMZ moiety and either a methoxy, a chloro or a bromo group at positions 3, 3,5 or 3,4,5 on the aromatic ring B exhibit antiproliferative activity ranging from 0.13 to 6.9 μM and selectivity toward MCF7 and MDA-MB-468 mammary cancer cells comparatively to other cell lines tested. Moreover, the most potent and selective PAIB-SOs bearing an iso-Bu group and either a 3,5-Cl (44), 3,5-Br (45) or a 3,4,5-OMe (46) on the IMZ moiety exhibit antiproliferative activity in the sub-micromolar range and high selectivity ratios toward mammary cancer cells. They stop the cell cycle of MCF7 cells in the G2/M phase and disrupt their cytoskeleton. Furthermore, our studies evidenced that PAIB-SOs bearing either an iso-Pr, a sec-Bu or an iso-Bu group are hydroxylated on the carbon atom adjacent to the IMZ (Cα-OH) but only PAIB-SOs bearing an iso-Bu group are bioactivated into PIB-SOs. Finally, PAIB-SOs 45 and 46 exhibit low toxicity toward normal cells and chick embryos and are thus promising antimitotic prodrugs highly selective toward CYP1A1-expressing breast cancer cells. The results came from multiple reactions, including the reaction of 3-Iodophenol(cas: 626-02-8Safety of 3-Iodophenol)

3-Iodophenol(cas: 626-02-8) 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. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Safety of 3-Iodophenol
