harness aromatic isocyanides as visible-light photocatalysts in the α-amino C(sp3)–H functionalization is herein presented. Actually, the three-component cross-dehydrogenative coupling of aromatic tertiary amines with isocyanides and water leads to amide products under very mild conditions in high yields and with a good substrate scope. While the reaction with aromatic isocyanides proceeds upon direct

Due to their tunable porous structure and photoelectric properties, conjugatedmicroporouspolymers (CMPs) have provided a new platform for visible-light driven photocatalysis. Some synthetic methods like Sonogashira, Suzuki, oxidative coupling and trimerization reactions have been commonly employed to synthesize photocatalytically active CMPs, but the copper promoted azide–alkyne click reaction is

A visible-light photoredox synthesis of α-amino amide or α-amino thioamide from N,N-dimethylaniline derivatives and aryl isocyanate or aryl isothiocyanate was developed. Bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato)iridium(III) (FIrpic) was found to be the effective catalyst among six catalysts screened. The reaction involves generation of α-aminoalkyl radicals from tertiary amines, followed
