Preparative procedure of dihalosulfenylation: Thiobisamines addition to unsaturated compounds in the presence of phosphorus oxyhalides and halides

Article abstract of DOI:10.1007/bf02757433

A new synthetic method was developed for β,β′-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.
