bioactive structural motifs. A new strategy to access chiral tertiary diarylmethanols through copper-catalyzed direct alkylation of (di)(hetero)arylketones by using Grignard reagents was developed. The low reactivity and the similarity of the enantiotopic faces of bis-aromatic ketones were partially overcome, which resulted in moderate to good yields and enantioselectivities.

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
