Regio‐ and stereoselective addition of a silyl‐substituted alkynyl sulfide to various terminal alkynes proceeds in the presence of a palladium catalyst to give ( Z )‐1‐thio‐1,3‐enynes, which are useful building blocks for the synthesis of polysubstituted 1,3‐enynes. Addition to internal alkynes also takes place under solvent‐free conditions (see scheme).
