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 the corresponding aryl chlorides, bromides and iodides in excellent yields. Aryl alcohols could serve as both aromatic electrophilic and radical synthetic equivalents during the reaction. Aryl alcohols which acted as aromatic electrophilic and radical synthetic equivalents were effectively converted to aryl halides via Cu mediated side-directed dehydroxyalkylative halogenation of C(aryl)-C bonds.
