Abstract

Abstract A novel compound constructed from polyoxometalate (H 3 PW 12 O 40, PW 12) and poly (amidoamine)(PA) was prepared at room temperature in an aqueous solution by an impregnation method. A series of novel 1, 3, 5-triaryl-2-pyrazoline derivatives was synthesized by the reaction between chalcone and phenylhydrazine in the presence of the title compound, PW 12/PA, in high yields. The structures of the compounds obtained were ...
