Abstract
In this paper, synthesize tungsten-substituted molybdophosphoric acid (H<sub>3</sub>PMo<sub>7</sub>W<sub>5</sub>O<sub>40</sub>·24H<sub>2</sub>O) and impregnated with kaolin clay by wetness impregnation method. The catalytic activity explored for synthesis of 3,4-dihydropyrimidin-2(1<italic>H</italic>)-ones (DHPM) <italic>via</italic> Biginelli reaction.
