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.
An operationally simple EosinYcatalyzed sulfenylation of hydrazones has been realized to afford a range of thioethers under visible light. The methodology provides high yields of thioethers under ambient conditions employing readily available and inexpensive starting materials. The reaction has broad substrate scope and is compatible with various functional groups.
