新型氮杂大环化合物的研究 Ⅱ.四吡唑类卟啉大环化合物的合成及配位性能

Studies on the New Aza-Macrocycles Ⅱ. Syntheses and Coordinating Behaviour of Tetrapyrazolic Porphyrinogenic Macrocycles

报道了几种四吡唑类卟啉大环化合物的合成及其对Ru^(2+)离子的配位性能.结果表明,配体环中4个sp^2杂化N原子均参与对Ru^(2+)配位,形成一个近似配位平面,另有两个相同或不同的轴向配体位于平面上下,形成稳定的八面体配位结构.根据轴向配体的配位稳定性可方便地将其进行交换.

We report in this paper the syntheses and complexing behaviour for Ru(Ⅱ) of four tetrapyrazolic porphyrinogenic macrocycles. Some of the ligands can form stable octahedral complex with Ru(Ⅱ). Two same or different axial ligands, such as DMSO, CH3CN or Pyridine, located above and below the complexing plane, respectively, can be easily thermoexchanged.
