Abstract A general method for the one-pot transformation of alkenes into abromoalkyl-arylsulfdes has been proposed based on the sulfenylation reaction by means of sulfenamides in the presence of phosphorus oxibromide. The plausible reaction mechanism and the results of reactions with a number of model alkenes such as cyclohexene, I-heptene, norbornene and other from the bicyclo[2.2.1] heptane series

−21.2) and for the reaction of p-nitrophenylsulfenyl chloride with styrene in carbontetrachloride (−39.5±1.5 and −22.0) were determined. In carbontetrachloride the activation volumes for the reactions of cyclohexene with o-and p-nitrophenylsulfenyl chlorides (−37.7±2.0 and −40.9±1.2 cm3 mol−1, respectively) are almost the same and coincide with the data for the reactions with styrene. The considerable
