Abstract

Abstract Reaction of terminal acetylenes with readily available and inexpensive copper and zinc halides and pseudo-halides and BTMSPO has been found to be an effective and general route for obtaining, in the absence of bases and under mild conditions, 1-halo-and 1- pseudohalo-1-alkynes in generally good yields.
