Abstract

Abstract The catalytic efficacy of different cesium salts of 12-tungstophosphoric acid as nanocatalysts was checked in Claisen-Schmidt condensation of aldehydes and ketones under solvent-free conditions to produce chalcones. The reaction is fast and environmentally benign with excellent selectivity for the synthesis of chalcones. Results of potentiometric titration and catalytic reactivity of the catalysts indicated that the catalytic reactivity should ...
