Aromatic thiols and 2-thiophenethiol react with ..beta..-chloro- and ..beta..-bromostyrene when heated to form the corresponding 1-phenyl-2-aryl(thienyl)thioethenes. The reaction begins at 80/sup 0/C and takes place effectively and strictly stereospecifically at 140-160/sup 0/C. The yield of the respective vinyl sulfides amounts to 70-95%. ..beta..-Bromostyrene reacts with thiophenol more slowly than ..beta..-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. Among the investigated thiols 2-thiophenethiol has the lowest reactivity.
