Abstract

A simple high-yielding preparation of aryl alkynyl sulfides is presented. The reaction of a chloroacetylene with a thiolate salt in the presence of an amine mediator (dimethylamine or N,N’-dimethylethylenediamine) yields the alkynyl sulfides in good yields. The alkynyl chloride is easily prepared from the parent alkyne contrasting sharply with the cumbersome synthesis of an alkynyl sulfonamide previously required.
