| 摘要: 本文发现混合三聚双席夫碱与过渡金属离子Cu(Ⅱ)、Ni(Ⅱ)、VO(Ⅱ)作用时,配体发生碳氮单键断裂后形成亚胺配合物。用室温及低温下ESR对反应进行了跟踪研究。所出现的活性中间体被Job's法确定其组份Cu:L为1:1,分子内溶剂轴向配位催化导致碳氮单键断裂。 |

| Abstract: It has been found that the mixed trimeric double Schiff bases react with transitional metal ions such as Cu(Ⅱ),Ni(Ⅱ),VO(Ⅱ) to form the inline complexes after the C-N single bond breaks in the part of ligands. The procedure of this reaction has been investigated with ESR method at room and low temperatures. The active intermediate present consists of the Cu I L of 1:1 ratio, determined by Job's analysis. The axial catalysis of coordination of intramolecular solvents results in the cleavage of C-N single bond. |
