Abstract

A nickel-catalyzed direct difluoromethylation of (hetero)aryl bromides with bromodifluoromethane (BrCF₂H) is described. This reaction features high efficiency, broad substrate scope and high functional group tolerance, providing a cost-efficient and straightforward route for applications in medicinal chemistry. Preliminary mechanistic studies reveal that a nickel-based, reductive cross-coupling catalytic cycle is involved in the reaction.

Key words: aryl bromide, bromodifluoromethane, difluoromethylation, nickel, reductive cross-coupling
