A Sb-containing Anderson-based polyoxomolybdate cluster, [(CH3)4N]4H8[Na5Sb3(Sb2Mo12O57)]·17H2O [1; (CH3)4N+ = TMA+], has been successfully synthesized by using an aqueous solution method and structurally characterized. In particular, UV-Vis spectroscopy has been employed to elucidate the stability of the polyoxoanions. Under mild conditions, the catalyst demonstrates high activity and selectivity for the sulfoxidation of various sulfides in the presence of hydrogen peroxide. For example, thioanisole undergoes up to 100% conversion and 100% sulfone selectivity at 25 °C in aqueous solution.
一种基于安德森结构的含 Sb 的多酸钼酸盐簇合物，[(CH3)4N]4H8[Na5Sb3(Sb2Mo12O57)]·17H2O [1；(CH3)4N+ = TMA+]，已通过水相法成功合成，并进行了结构表征。特别地，采用紫外-可见光谱法阐明了多酸阴离子的稳定性。在温和条件下，该催化剂在过氧化氢存在下对各种硫化物的氧化表现出高活性和选择性。例如，在水溶液中，苯硫醚在 25°C 下可达到 100%的转化率和 100%的砜选择性。
