A new synthetic method was developed for beta,beta'-dihaloalkyl sulfides (halogen chlorine or bromine) by reaction of thiobisamines with olefins and alkynes in the presence of the appropriate phosphorus halides. The reaction proceeds along electrophilic mechanism affording trans-addition products. The highest yields of the target products were obtained at POBr3 or POCl3 application.
