1-[N-(benzyl)amino]-methyl-H-phosphinic acid were prepared by the addition of bis(trimethylsilyl)phosphonite to the corresponding imines and subsequent methanolysis of the addition products. Treatment of the 2-pyridyl- and 1-(4-pyridyl)-1-(benzylamino)-methyl-H-phosphinic acids with aqueous mineral acids leads to cleavage and formation of the corresponding secondary amines and phosphorous acid (H 3 PO 3 ).
1-[N-(苄基)氨基]-甲基-H-次膦酸的新2-吡啶基、3-吡啶基和4-吡啶基衍生物是通过将双(三甲基甲硅烷基)亚膦酸酯加入相应的亚胺中并随后进行甲醇分解来制备的加成产物。用无机酸水溶液处理 2-吡啶基-和 1-(4-吡啶基)-1-(苄氨基)-甲基-H-次膦酸导致裂解并形成相应的仲胺和亚磷酸 (H 3 PO 3 )。
