Abstract
Acylthiosulfenyl halides, phosphorylsulfenyl halides, and thiophosphorylsulfenyl halides are added to monoolefins, multiolefins and acetylenic compounds. 1,2-Markownikov oriented adducts are the principal products when conjugated diolefins are employed as the starting feedstock. Anti-Markownikov adducts are obtained as major products when unsymmetrical monoolefins and nonconjugated multiolefins are used as the starting material. The addition reactions are conducted at low temperatures.
