Palladium-catalyzed direct arylation of 4-hydroxycoumarins with arylboronic acids via C–OH bond activation
摘要:
Operationally simple PdCl2-Catalyzed direct arylation of 4-hydroxycoumarins with arylboronic acids via C-OH bond activation under mild conditions is described, which gave rise to the corresponding 4-arylcoumarins in good to excellent yields. (c) 2009 Elsevier Ltd. All rights reserved.
