Nickel-Catalyzed C(sp3)–H Arylation of Diarylmethane Derivatives with Aryl Fluorides

A novel nickel-catalyzed C­(sp3)–H arylation with nonactivated aryl fluorides is reported. The use of 1,3-bis­(2,4,6-trimethylphenyl)­imidazol-2-ylidene (IMes) as a ligand was found to be critical to the success of the reaction. This new method enables the synthesis of a wide range of triarylmethane derivatives.
