摘要：

A first observation of the direct alkynyl group transfer from silicon to copper is reported. The silicon group of alkynylsilanes was smoothly replaced by copper (I) chloride in DMI to give the corresponding copper (I) acetylides. This transformation was applied to the synthesis of alkynyl ketones catalyzed by CuCl. (C) 1997 Elsevier Science Ltd.
