Аннотация:A new method for the synthesis of beta,beta'-dilialoalkyl vinyl sulfides was proposed. The method is based on reactions of alkenesulfenamides with olefins in the presence of POCl3 or POBr3. The reactions with cage olefins (norbornene, norbornadiene, camphene, and dimethyl 5,6-di-endo-norbornenedicarboxylate) afford stable products, while vinylsulfenylation of a conformationally labile olefin (cyclohexene) give products that decompose during their isolation.
