A new, convenient and high yielding procedure for the preparation of diethyl α-aminophosphonates in water by one-pot reaction of aldehydes, amines, tri/dialkyl phosphites in the presence of a low catalytic amount of [Cu(3,4-tmtppa)](MeSO4)4 (0.16 mol%) as a highly stable and re-usable catalyst is described.
在低催化量的[Cu(3,4-tmtppa)存在下,通过一锅反应醛,胺,亚磷酸三/二烷基酯,在水中制备α-氨基膦酸二乙酯的新型,便捷且高收率的方法描述了作为高度稳定且可重复使用的催化剂的](MeSO 4)4(0.16 mol%)。
