Zinc-catalyzed hydrosulfenylation of alkenes can be performed in various solvents,
and the corresponding products are obtained regioselectively. Dihydrosulfenylation
of alkynes with thiols can also be achieved by using a zinc catalyst, and the reaction
is preferentially promoted over monohydrosulfenylation. The reaction can also give
dithioacetals regioselectively in excellent yields.
Key words
