On treatment with two equivalents of NaNH2 in liquid ammonia the enyne sulfides RCC-CH=CHSEt (cis-isomers, where R is an aryl or a hetaryl) affords sodium salts of 1,3-diynes.The latter react with ethyl bromide to produce disubstituted diynes RCC-C

The thiylation af monosubstituted biacetylenes in ammonia solution is regio- and stereoselective at the terminal acetylenic bond.In the case of biacetylenic alcohols the regioselectivity is destroyed, and this is due to the electron-withdrawing effect of
