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 excellent yields. The alkynyl chloride is easily prepared from the parent alkyne.}, url = {http://dx.doi.org/10.1039/c5ob00494b}, issn = {1477-0539} }
