We report the first examples of N-heterocyclic silylene-stabilized monocoordinate Ag(I) cationic complexes weakly bound to the free arene rings (C6H6, C6Me6, and C7H8). Further, the application of these electrophilic Ag(I) complexes as catalysts has been investigated toward A3-coupling reactions, which afforded a series of propargylamines in good to excellent yields with low catalyst loading under a solvent-free condition (19 examples).

A new α-C(sp3)-H alkynylation of unactivated tertiary aliphatic amines with 1-iodoalkynes as radical alkynylating reagents in the presence of [Au2(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(sp3)-C(sp) bond formation. The mild, convenient, efficient, and highly selective C(sp3)-H alkynylation reaction shows excellent regioselectivity and good functional-group compatibility. A scale-up to gram quantities is possible with sunlight used as a clean and sustainable energy source.
