A highly regio- and stereoselective CuCl-mediated carbometallation reaction of 3-aryl-substituted secondary propargylicalcohols with alkyl, aryl, vinyl or allyl Grignard reagents for the synthesis of fully-substituted allylic alcohols was developed. The R2group from the Grignard reagent was successfully introduced to the 2-position of the propargylicalcohols due to the chelation of metal atom with
