A Highly Efficient Gold-Catalyzed Photoredox α-C (sp
A new α-C(sp 3) H alkynylation of unactivated tertiary aliphatic amines with 1-iodoalkynes as radical alkynylating reagents in the presence of [Au 2 (μ-dppm) 2] 2+ in sunlight provides propargylic amines. Based on mechanistic studies, a C C coupling of an α-aminoalkyl radical and an alkynyl radical is proposed for the C(sp 3) C(sp) bond formation.
