Photocatalytic α-aminoalkyl radical addition of amines mediated by benzophenone under visible light

Abstract

Herein, we report the intermolecular photocatalytic addition of amines and alkenes using metal-free conditions. Benzophenone was added as a photosensitizer to accelerate the single electron transfers, H-atom transfers and generation of α-aminoalkyl radicals. N-Alkyl anilines were alkylated with high selectivity and broad substrate scope.
