two-stage method for the synthesis of a boron-containing complexone on the basis of aminomalonic acid was proposed. The products were studied by multinuclear NMR spectroscopy, IR absorption spectroscopy, and ESI mass spectrometry at all the stages of synthesis. The product (NBu4)[2-B10H9NHC(CH3)NHCH(COOEt)2] was structurally characterized by singe-crystal X-ray diffraction. The complexation reaction
摘要提出了一种基于氨基丙二酸合成含硼配合物的两步法。在合成的所有阶段,通过多核NMR光谱,IR吸收光谱和ESI质谱对产物进行了研究。通过单晶X射线衍射对产物(NBu 4)[2-B 10 H 9 NHC(CH 3)NHCH(COOEt)2 ]进行结构表征。研究了氨基丙二酸的硼酸酯化衍生物与Hf(NEt 2)4和Hf(OBu)4的络合反应。
