Nickel-catalyzed Suzuki–Miyaura cross-couplings of aldehydes

Classical Suzuki-Miyaura couplings require wasteful electrophilic coupling partners and an exogenous base often engaging in side-reactions. Here, the authors report an alternative Suzuki-type synthesis of biaryls, involving the base-free nickel-catalyzed deformylative coupling of aldehydes with organoboron reagents.
