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.

可回收的三苯基铋（V）双氟辛烷磺酸酯催化合成二氢嘧啶酮

三苯基铋（V）bisperfluorooctanesulfonate博士3的Bi（OSO 2 ç 8 ˚F 17 ）2成功地被处理的pH的合成3 BiCl 2为C 8 ˚F L7 SO 2OAg，并且具有空气稳定性，耐水性，高热稳定性和强路易斯酸性的性质。该配合物在温和条件下通过芳族醛，1,3-二羰基化合物和尿素的三组分反应对二氢嘧啶酮（DHPM）的合成具有很高的催化效率。此外，在五个周期的测试中，它可以重复使用而不会失去活动。因此，这里我们提供了一种方便有效的制备二氢嘧啶酮的方法。
