here the iron-catalyzedcross-couplingreaction of alkyl vinyl halides with thiols. While many works are devoted to the coupling of thiols with alkyl vinyl iodides, interestingly, the known S-vinylation of vinylbromides and chlorides is limited to 1-(2-bromovinyl)benzene and 1-(2-chlorovinyl)benzene.

Phenylthiotrimethylsilylmethyllithium(1) was reacted with a variety of electrophiles, including somecontaining two functional groups. α-Phenylthiolketones were obtained from the reaction with esters. The anion(1) underwent either 1,2- or 1,4-addition, depending on the conditions used, with 2-cyclohexen-1-one.

β-Hydroxythioacetals or β-hydroxysulfides, prepared by the reactions of α-lithio thioacetals or α-lithio sulfides with aldehydes or ketones, were converted into vinylsulfides or olefins in good yields by the treatment with TiCl4 and Zn.

The title reactions can be explained by WagnerâMeerwein rearrangement of α-thio carbocations (thionium ions) to β-thio carbocations; this unusual reactivity may be due to superelectrophilic activation by aluminium chloride.

The synthesis of vinyl sulfides through the coupling reaction of thiols with vinyl iodides, bromides, and chlorides is described. The thiols can couple with aryl iodides in the presence of only 0.5 mol % Cu2O without the need for an ancillary ligand. In the presence of 5 mol % of Cu2O and 10 mol % 1,10-phenanthroline as the ligand, the more challenging alkyl vinyl bromides can also be coupled with thiols, giving the vinyl sulfides in good to excellent yields.
