In 2019,Chemical Communications (Cambridge, United Kingdom) included an article by Xu, Rui; Cai, Chun. Synthetic Route of C33H24IrN3. The article was titled 《Three-component difluoroalkylation-thiolation of alkenes by iron-facilitated visible-light photoredox catalysis》. The information in the text is summarized as follows:
An efficient synthesis of(arylthio)difluoroalkanoates R1SCHR2CHR3CF2CO2Et [R1 = 4-MeC6H4, 4-FC6H4, PhCH2, 2-pyridinyl, 2-pyrimidinyl, etc.; R2 = n-hexyl, Ph, 4-MeOC6H4, etc., R3 = H; R2R3 = (CH2)3] has been developed via three-component difluoroalkylation-thiolation of alkenes R2CH:CHR3 with thiols R1SH and Et difluorobromoacetate using iron-facilitated visible light photoredox catalysis. The Csp3-Csp3 and Csp3-S bonds were simultaneously constructed smoothly under mild conditions. The reaction exhibits a broad substrate scope of alkenes and thiols with good to excellent yields. In the experiment, the researchers used fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Synthetic Route 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.Synthetic Route of C33H24IrN3
