Zinc oxide as a regioselective and heterogeneous catalyst for the synthesis of chalcones at room temperature

More, Parmeshwar E.,Bandgar, Babasaheb P.,Kamble, Vinod T.

, p. 30 - 32 (2012/10/30)

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 α, β-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.
