hydrothiolation of alkenes with thiols was achieved in the presence of 4-toluenesulfonic acid. Through this procedure, Markovnikov-type sulfides were synthesized in excellent yields, and the formation of anti-Markovnikov-type sulfides was suppressed. Furthermore, the combination of numerous aryl alkenes with arenethiols or alkyl thiols was achieved using the procedure.

examples of transition-metal-catalyzed hydrothiolation of alkynes, the corresponding catalytic addition of thiols to alkenes has remained undeveloped. However, a novel Pd-catalyzed addition of thiols to alkenes bearing a heteroatom, such as oxygen and nitrogen, is found to proceed under mild conditions to give the corresponding Markovnikov adducts, regioselectively, in good yields.

Catalyst-controlled divergent reactions of thiophenols with alkenes bearing heteroatoms have been developed. Markovnikov-type hydrothiolation products and thioacetals were synthesized selectively by switching copper catalysts.
