A novel enantioselective copper‐catalyzed arylation of benzylic C−H bonds, using alkylarenes as a limiting reagent, has been developed. A chiral bisoxazoline ligand bearing an acetate ester moiety plays a key role in both the reactivity and enantioselectivity of the reaction. The reaction provides efficient access to various chiral 1,1‐diarylalkanes in good yields with good to excellent enantioselectivities
