Catalytic Asymmetric Cross‐Couplings of Racemic α‐Bromoketones with Arylzinc Reagents

Nickel box: The first catalytic asymmetric method for cross-coupling arylzinc reagents with α-bromoketones has been developed (see scheme). This stereoconvergent carbon–carbon bond-forming process occurs under unusually mild conditions and without activators, thereby allowing the generation of potentially labile tertiary stereocenters.
