Visible light promoted fluoroalkylation of hydrazones using 4-perfluoropyridine sulfides as fluoroalkyl radical sources is described. The process can proceed in neutral and reductive modes delivering either hydrazones or hydrazines, respectively, depending on structure of starting substrates and reaction conditions. For the reductive process, ascorbic acid is used as a terminal reductant, which recycles the photocatalyst and serves as a source of hydrogen towards nitrogen-centered radicals. (Figure presented.).
Transaminases as suitable catalysts for the synthesis of enantiopure β,β-difluoroamines
García-Ramos, Marina,Lavandera, Iván
, p. 984 - 988 (2022/02/16)
Transaminases have shown the ability to catalyze the amination of a series of aliphatic and (hetero)aromatic α,α-difluorinated ketones with high stereoselectivity, thus providing the corresponding β,β-difluoroamines in high isolated yields (55–82%) and ex
