Nickel-catalyzed monofluoromethylation of (hetero)aryl bromides via reductive cross-coupling.

A mild and efficient nickel-catalyzed direct monofluoromethylation of (hetero)aryl bromides by reductive cross-coupling has been developed. This method exhibits good efficiency, wide functional-group compatibility, and suitability for aryl and heteroaryl bromides with abundant industrial raw material BrCH2F. This strategy provides an efficient way to synthesize monofluoromethylated molecules for drug discovery.
