Pd(0)-Catalyzed Diarylation of sp3 C-H Bond in (2-Azaaryl)methanes

A highly efficient and selective palladium-catalyzed diarylation of (2-azaaryl)methanes at the methyl group is described. Aryl chlorides proved reactive enough. A palladium eta(3)-azaallyl intermediate has been identified on the basis of DFT studies.
