A metal-free, and environment benign iodine-catalysed protocol has been developed for the regioselectivesynthesis of β-hydroxysulfides in good to excellent yields from easily accessible styrenes and thiophenols. The reaction involves single step CS and CO bonds construction.

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;
