We have developed a highly efficient method for the chemoselective nucleophilicsubstitution of tertiary and secondary benzylic alcohols with aliphatic and aromatic thiols in the presence of catalytic amounts of indium(III) triflate under mild conditions. A broad range of unsymmetrical sulfides were synthesized in excellent isolated yields (89–99 %) by using this approach.
