We first report the direct ortho C–Hamidation of arenes with azides by using a novel and inexpensive RuHCl(CO)(PPh3)3 catalyst. The reaction proceeds efficiently in high yield over a broad range of substrates without requirement of any additional silver salt or additive.

The Cu(OAc)(2)-catalyzed, O-2-mediated amidation of 2-phenylpyridine via C-H bond activation is reported. A variety of nitrogen reagents including sulfonamides, carboxamides, and anilines participate in the reaction in moderate to good yields.
