    Project supported by the National Basic Research Program of China (973 Program, No. 2015CB931900), the National Natural Science Foundation of China (Nos. 21425208, 21672238, 21332010, 21421002), and the Strategic Priority Research Program of the Chinese Academy of Sciences (No. XDB20000000).

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
