Direct C3-alkenylation of pyridin-4(1H)-one via oxidative Heck coupling
摘要:
Oxidative Heck coupling of pyridin-4(1H)-one via palladium(II)-catalyzed C-H bond activation has been achieved in moderate to good yields. The coupling occurred selectively at C3 position. Pivalic acid was found to be an effective additive to promote this alkenylation. (C) 2012 Elsevier Ltd. All rights reserved.
