Six 1,1-diaryl-2-arylthioethylenes were obtained by displacement of chloride or bromide ion from diaryl-halogeno ethylenes by aryl thiolateions in amidic solvents.

cascade reaction of aryl alkynoates has been developed with thiol as a coupling partner. This radical process has been demonstrated to proceed through S–H bond cleavage, thiolation of alkynoate, aryl migration, and decarboxylation. This reaction tolerates a wide scope of substrates resulting in good chemical yields, which provides an easy and practical strategy for preparation of trisubstituted vinyl
