Alkynylation of alpha-halocarbonyl compounds--a stille-type cross-coupling for the formation of C(sp)-C(sp3) bonds under neutral conditions.
A direct alkynylation of readily available alpha-halo esters and amides with high yields is described herein; a distinct switch from diyne formation to alkynylation products was attained under neutral conditions.
