摘要

A simple and highly efficient synthesis of β, β'-dihydroxy sulfides has been achieved by ring opening of epoxides with mercaptoethanol using catalytic amount of benzyltrimethylammonium hydroxide (Triton B) under solvent-free conditions. Excellent regioselectivity was found for aliphatic unsymmetrical epoxides, with nucleophilic attack at the less-hindered carbon atom of the epoxide. However, this regioselectivity was not ...
