An enantioselective Ni-catalyzed reductive cross-coupling of acid chlorides with racemic secondary benzyl chlorides in the presence of Mn0 as a stoichiometric reductant generates acyclic α,α-disubstituted ketones in good yields and high enantioselectivity. The mild, base-free reaction conditions tolerate various functional groups on both coupling partners.
