Zinc oxide as a regioselective and heterogeneous catalyst for the synthesis of chalcones at room temperature
摘要:
Zinc oxide catalyzed synthesis of chalcones has been carried out under solvent-free conditions at room temperature. Activated as well as unactivated aromatics smoothly underwent Friedel-Crafts acylation with alpha,beta-unsaturated acid chlorides furnishing excellent yields of the corresponding chalcones. The zinc oxide can be recovered and reused at least three times without any appreciable loss in activity. (C) 2012 Elsevier B.V. All rights reserved.
