描述了新的咪唑-2-基-(氨基)甲基膦酸,膦酸酯次膦酸酯和氧化膦的有效合成。合成方法基于将磷物质亲核加成到咪唑2衍生的亚胺上。此外,还发现,将咪唑-2-基-(氨基)甲基膦酸酯与HCl或H 2 SO 4水溶液加热会导致其分解,从而导致C-P键断裂,消除含磷片段并形成相应的仲咪唑-2烷基胺。假定了裂解的机械途径。

Abstract The paper describes solution studies of Cu(II) and Ni(II) complexes of new N-substituted imidazole-2-yl(amino)methylphosphonates. The presence of the 2-imidazole ring makes studied phosphonates very efficient ligands, with nickel(II) ions chelation much more effective than by the previously designed 4-imidazole analogs.
