Аннотация:A new method for the synthesis of di(2-haloalkyl) disulfides and beta,beta'-dibromothiacyclanes was proposed based on reactions of dithiobisamines with olefins in the presence of PBr3, PBr5, or POBr3. Reactions with alkenes lead to di(2-bromoalkyl) disulfides. Analogous products and heterocyclic dibromosulfides, i.e., the products of addition of one dithiobisamine molecule to both double bonds of a diene, are obtained in reactions with alkadienes.
