A copper-catalyzed hydroxysulfenylation of alkenes was achieved using disulfides in the presence of n-Bu4NI and H2O. The procedure smoothly proceeded under air atmosphere, and the corresponding β-hydroxysulfides were obtained with regio- and anti-selectivity in good yields. Furthermore, a reaction using diselenides effectively produced the expected β-hydroxyselenides. These reactions could use both

A visible-light-induced and efficient one-pot synthesis of β-hydroxysulfides from olefins, thiosulfonates and HCOOCs using an EDA complex strategy under air atmosphere at room temperature has been disclosed. A plausible radical involved mechanism is proposed. During the reaction process, formates play a crucial role: first, as donors in the EDA complex; second, as providers of the hydrogen source;

Herein, sulfinylchlorides and styrenes have been exploited to afford either β-hydroxy-phenylethyl sulfides catalyzed by homogenous ZnCl2, or β-chloro-phenylethyl sulfones mediated by heterogeneous CuO nanoparticles (NPs). The key to achieve such a divergent synthetic strategy is the controlled disproportionation process of sulfoxide-onium ions, induced by different metal complexes. Owing to the mild
