Gold-catalyzed oxidations of thioalkynes with 8-methylquinoline oxides afford 2-phenylthioketenes that can be trapped efficiently with alcohols. The synthetic utility is manifested by terminal and internal thioalkynes over a wide scope, bearing esters, ke

Treatment of dichloroacetylene with two equivalents of a thiol and two equivalents of potassium hydride in THF solution affords the corresponding bis(R-thio)acetylene in high yield.

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.

The reaction of arenethiols ArSH (Ar = p-Tol, Ph, 4-ClC6H4) with tetrachloroethylene, initiated by UV irradiation or benzoyl peroxide, leads to the formation of mixtures of unsaturated and saturated products, i.e., aryl α,β-dichlorovinyl and β,β-dichlorovinyl sulfides, trichlorovinyl sulfides, 1,1,2,2-tetrachloroethyl and 1,2,2,2-tetrachloroethyl sulfides, diaryl disulfides, and isomeric diarylthiodichloroethenes.During discussion of the reaction mechanism, which involves reaction of the ArS radical with the tetrachloroethylene, evidence is given in favor of an α,β-chlorotropic rearrangement of the intermediate radical ArSCCl2CCl2 to the radical ArSCClCCl3.After the appropriate treatment it is possible to isolate the aryl trichlorovinyl sulfides in a mixture with small amount of aryl α,β-dichlorovinyl and aryl β,β-dichlorovinyl sulfides.
