The reactions of singlet oxygen with 2-chloroethyl ethyl sulfide and 3-chlorothiane are reported. In both cases elimination of HCl to produce α,β-unsaturated sulfoxides is observed. The experimental results implicate a hydroperoxy sulfonium ylide as a transitionstate or intermediate in an E2 or E1 cb elimination, respectively.

mixture of dioctenyl sulphoxides by way of alkenesulphenic acid–dialkyl sulphine interconversions. Benzenesulphenic acid, methanesulphenic acid, and ethoxycarbonylmethanesulphenic acid, conveniently generated by thermolysis of 1-cyano-2-alkyl(or aryl)sulphinylethanes, underwent intermolecular addition to unactivated and activated alkynes regioselectively to give alkenyl sulphoxides in good yields.
