A simple, general, and highly regioselective procedure has been developed for the one-potsynthesis of β-hydroxysulfides in good yields from various styrenes and disulfides by cleavage of the S–S bond with a Zn/AlCl3 system in aqueous acetonitrile at 80 °C and in the presence of oxygen.
An environmentally benign and highly efficient procedure has been developed for the direct one-pot synthesis of beta-hydroxysulfides in good yields under neutral conditions from alkenes and thiophenols in the presence of aerial oxygen using beta-cyclodextrin in water. This protocol tolerates a wide variety of functional groups or substrates and does not require the use of either acid or base catalysts. beta-Cyclodextrin can be recovered and reused for a number of runs without any loss of activity.

Markovnikov or anti-Markovnikov selective thiol–ene click (TEC) reactions and the synthesis of β-hydroxysulfides via aerial dioxygen activation are prevalent C–S bond forming reactions of styrenes and thiophenols. Herein, by choosing appropriate environments using solvents with additives or neat conditions, any one of these three reactions was achieved exclusively in excellent yields.
