In 2019,Advanced Synthesis & Catalysis included an article by Li, Lixin; Ma, Yan-Na; Tang, Mi; Guo, Jing; Yang, Zhen; Yan, Yizhe; Ma, Xiantao; Tang, Lin. Electric Literature of C33H24IrN3. The article was titled 《Photoredox-Catalyzed Oxydifluoroalkylation of Styrenes for Access to Difluorinated Ketones with DMSO as an Oxidant》. The information in the text is summarized as follows:
By taking advantage of DMSO (DMSO) as an oxidant, the photoredox-catalyzed alkene oxydifluoroalkylation for formal C(sp3)-CF2R and C(sp2)=O formation is disclosed for the first time. This difunctionalization reaction employs readily available styrenes as the substrates and bromodifluoro compounds as the difluoroalkylating reagents, which can afford the difluorinated ketones in acceptable yields with excellent regioselectivity. Experiments indicate that fac-Ir(ppy)3-catalyzed oxydifluoroalkylation can proceed smoothly under base-free conditions in the presence of AgTFA. In the experiment, the researchers used fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Electric Literature of C33H24IrN3)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) 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.Electric Literature of C33H24IrN3
