Hydrogermylation of Alkenes via Organophotoredox-Initiated HAT Catalysis

Abstract

This Letter discloses the straightforward hydrogermylation of olefins under visible-light organophotoredox-initiated HAT catalysis conditions to yield primary and secondary alkyl germanes at room temperature. The protocol is operationally simple, metal-free, and tolerant of various functional groups. The synthesized alkyl germanes proved to be highly robust toward acidic, basic, or oxidizing conditions and chemical transformations of C_sp²-GeEt₃ or C_sp²-BPin functionalities in their presence.
