Dehydroxyalkylative halogenation of C(aryl)-C bonds of aryl alcohols.

We herein report Cu mediated side-directed dehydroxyalkylative halogenation of aryl alcohols. C(aryl)−C bonds of aryl alcohols were effectively cleaved, affording corresponding aryl chlorides, bromides and iodides in excellent yields. Aryl alcohols could serve as both aromatic electrophilic and radical synthetic equivalents during the reaction.
