A highly efficient one-pot method for the synthesis of a variety of α-aminophosphonates via the one-pot three-component reaction of aldehyde, amine, and phosphite has been developed using only 2 mol % HfCl4 as the catalyst. The NMR evidence strongly indicated the catalytic roles of Hf(IV) on the activation of aldehyde, phosphite, and imine intermediate.
已经开发出仅使用2mol%的HfCl 4作为催化剂通过醛,胺和亚磷酸酯的一锅三组分反应来合成各种α-氨基膦酸酯的高效一锅法。NMR证据强烈表明Hf(IV)对醛,亚磷酸酯和亚胺中间体的活化具有催化作用。
