Abstract

Abstract Zirconocene bis (perfluorobutanesulfonate)[Cp 2 Zr (OSO 2 C 4 F 9) 2· 2H 2 O] was successfully synthesized by treatment of Cp 2 ZrCl 2 with C 4 F 9 SO 3 Ag, 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 ...
