Zirconocene bis(perfluorobutanesulfonate) [Cp2Zr(OSO2C4F9)2·2H2O] was successfully synthesized by treatment of Cp2ZrCl2with C4F9SO3Ag, 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 α-aminophosphonates via Kabachnik–Fields reaction of aldehydes/ketones, amines and diethyl phosphite under mild and solvent-free conditions. Furthermore, it can be reused without loss of activity in a test of five cycles. Compared with our previously reported complex of Cp2Zr(OSO2C8F17)2·3H2O·THF, this complex showed better catalytic activity.
