Catalyst-free visible light-promoted defunctionalization of alkyl isocyanides with a hydrosilane through C–N bond cleavage

Abstract

A radical initiator-free defunctionalization reaction of alkyl isocyanides with a hydrosilane has been established through C–N bond cleavage under catalyst-free visible light irradiation. Various alkyl isocyanides participated in the defunctionalization with tris(trimethylsilyl)silane under blue light irradiation at room temperature, delivering the reduced products in good yields with high chemoselectivity.
