Abstract
Abstract An efficient one-pot route to synthesize tertiary alcohol compounds using Barbier– Grignard reaction of unactivated alkyl or aryl bromides with ester in THF at 65 C catalyzed by CuO has been developed and systematically investigated. A wide range of substituted tertiary alcohol compounds were obtained in good to high yields. The reaction is highly chemoselective. The mechanism involving the leaving group of R 2 O-group is discussed.
