Chloramine-T-Mediated Oxidation of Benzylic Alcohols Using Indium(III) Triflate

: The efficient oxidation of benzylic alcohols to carbonyl compounds was performed using chloramine-T and a catalytic amount of indium(III) triflate. The primary benzylic alcohols were converted to the corresponding aldehydes in a good yield, and the secondary benzylic alcohols were oxidized to ketones in a high yield. The optimized reaction conditions required 0.3 eq of indium(III) triflate and the use of acetonitrile as a solvent.
