Aldehydes are a kind of important synthons and reagents in organic synthesis. The efforts on transformations of aldehydes are highly rewarding and have always attracted considerable attention. Herein, a cross-coupling of aldehydes with α-haloboronates has been achieved under dual nickel/photoredox catalysis system. Considering the α-haloboronates can be easily obtained from aldehydes with our deoxygenative
