The addition of perchloric acid in the addition reactions of sulfenyl chlorides to olefins gives rise to a doping effect, which exceeds the analogous effect of lithium perchlorate.Analysis of the dependence of rate of the model reactions and the yields of the doping products on the perchloric acid and lithium perchlorate concentrations showed that the doping additions can operate by two mechanisms, i.e., by the mechanism of a normal salt effect in the controlling state and by a mechanism of ion-pair exchange in the subsequent fast stages.

The products and the kinetic relationships of the reactions of chlorothiocyanogen, dithiocyanogen, and 2,4-dinitrobenzenesulfenyl halides with allylbenzenes and styrenes in acetic acid were investigated in the presence of lithium perchlorate and without additions.Considerable variation was found in the electrophilicity of the sulfur-containing reagents (the formation of only products from normal addition and/or solvated adducts and the products from skeletal rearrangement).The nature of the reagent has an effect on the degree of the effect of strong electrolytes in the control of the competing reactions.The kinetic relationships governing the reactions were investigated, and an analysis was made of the data from the reactions of sulfenyl halides with styrenes.
