Liquid-phase thermal reactions of phenylacetylene with the system arene(hetarene)thioldiselenide at 110-180°C proceed through conjugate addition to the phenylacetylene triple bond of one alkylselanyl and one arene(hetarenesulfanyl groups to form 2-alkylse

Aromatic thiols and 2-thiophenethiol react with β-chloro- and β-bromostyrene when heated to form the corresponding 1-phenyl-2-aryl(thienyl)thioethenes.The reaction begins at 80 deg C and takes place effectively and strictly stereospecifically at 140-160 deg C.The yield of the respective vinyl sulfides amounts to 70-95percent. β-Bromostyrene reacts with thiophenol more slowly than β-chlorostyrene,and this is due to the inhibiting action of the hydrogen bromide, which acts as a trap for the thiyl radicals and gives rise to decomposition of the obtained 1-phenyl-2-phenylthioethene.A mong the investigated thiols 2-thiophenethiol has the lowest reactivity.
