杂志文章abstract::Catalytic disulfenylation reaction of alkenes by common Lewis acids has been investigated in detail. While reactions by FeCl(3) were feasible with cycloalkenes and other simple alkenes, much faster and excellent conversions were possible by AlCl(3) even with the substrates less reactive toward FeCl(3). ...
