chelation‐assisted direct intermolecular arylation using an N‐heterocyclic carbene and phosphine ligands (see scheme; IMes=1,3‐bis(2,4,6‐trimethylphenyl)imidazol‐2‐ylidene). The reaction is operationally simple, proceeds under mild reaction conditions to afford mono‐ or diarylated products in excellent yields, and is applicable to the arylation at the sp3 or sp2CH bonds of 2‐pyridyl‐containing aryl, vinyl
