The free-radical reaction of diaryl disulfides ArSSAr with CHCl=CCl2 leads to aryl β,β- and α,β-dichlorovinyl sulfides, trichlorovinyl sulfides, and the trichloroethylene dimer 1,1,3,3,4,4,-hexachloro-1-butene.In the reaction of diaryl disulfides with tetrachloroethylene aryl trichlorovinyl sulfides and hexachloro-1,3-butadiene are formed.A reaction mechanism involving reaction of the vinyl radicals CCl2=C.Cl, CCl2=C.H, adn CHCl-C.Cl with the arylthiyl radical is proposed.

During the free-radical thiylation of trichloroethylene with organic thiols β,β-dichlorovinyl sulfides are formed in a single stage.The reaction of alkanethiols with tetrachloroethylene under analogous conditions leads to trichlorovinyl sulfides.Oxidation of β,β-dichlorovinyl sulfides with hydrogen peroxide in acetic acid leads to the corresponding β,β-dichlorovinyl sulfones.
