Abstract

Triphenylbismuth(V) bisperfluorooctanesulfonate Ph3Bi(OSO2C8F17)2 was successfully synthesized by treatment of Ph3BiCl2 with C8Fl7SO2OAg, and was found to have the nature of air-stability, water tolerance, high thermal stability and strong Lewis acidity. This complex showed high catalytic efficiency for the synthesis of dihydropyrimidinones (DHPMs) via three-component reaction of aromatic aldehydes, 1,3-dicarbonyl compound and urea under mild conditions. Furthermore, it can be reused without loss of activity in a test of five cycles. Hence, here we provide a convenient and efficient method for preparation of dihydropyrimidinones.
