Z-Enynes, RCH=CHC≡CH (R= phenyl, 2-furyl, 2- and 3-thienyl and 3-pyridyl) can be obtained in ～ 40% overall yields and with a stereoselectivity of> 95% by Pd/Cu-catalyzed cross-coupling of the readily available enyne sulfide HC≡CCH=CHSC2H5
INVESTIGATION IN THE REGION OF BIACETYLENE DERIVATIVES XLIII. THIYLATION OF MONOSUBSTITUTED BIACETYLENES IN AMMONIA SOLUTION

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
