Schrauzer的钼-半胱氨酸体系,是固氮酶模拟物中研究得最深入的体系之一,最近,又发展成为钼-胰岛素体系,选择性有了进一步提高。关于这一体系的配位体结构和活性关系的研究已作了一些工作,其中,最重要的一点是硫的配位,即与钼相连接的配位基团必须带有—SH基才有活性。但关于桥连原子对活性的影响,则尚未见有报道。 Schrauzer’s molybdenum-cysteine ​​system, one of the most studied systems for nitrogenase-simulants, has recently evolved into a molybdenum-insulin system with further improvements in selectivity. Some work has been done on the relationship between ligand structure and activity of this system. Among them, the most important point is that the coordination of sulfur, that is, the coordination group with molybdenum must have -SH group active. However, there is no report on the effect of bridging atoms on the activity.
