Annulation of benzamides with [60]fullerene through palladium(II)-catalyzed C-H bond activation.

摘要: Palladium-catalyzed heteroannulation of N-sub- stituted benzamides with (60)fullerene, which proceeds through direct sp 2 C-H bond activation to form 7-membered ring pallada-intermediate C60 ,l ed formation (60)fulleroisoquinolinones in moderate good yields (8- 64% based on recovered C60). A plausible reaction pathway is proposed.
