A simple, mild, and high yielding procedure for the halogenation of allylic and benzylic alcohols using a combination of SOCl2, benzotriazole, and potassium halides in DMF is described. The effectiveness of the protocol is manifested in its selectivity towards allylic and benzylic alcohols whereas other simple alcohols such as primary, secondary, and tertiary are found to be unreactive.
