Oxidation of organosilanes is one of the pivotal reactions in organic synthesis and the corresponding products of silanols are widely as raw materials in industrial processes. In this paper, a new type of polyoxomolybdate containing mixed-valence antimony, [SbVSbIII4Mo18O66]7− (1a), has been isolated as tetramethyl ammonium salt in aqueous solution. The compound was structurally characterized by FT-IR
有机硅烷的氧化是有机合成中的关键反应之一,相应的硅烷醇产物已广泛用作工业过程的原料。本文提出了一种新型的含混合价锑的聚氧钼酸盐[Sb V Sb III 4 Mo 18 O 66 ] 7-(1a),已分离为四甲基铵盐的水溶液。该化合物在结构上通过FT-IR,XPRD,TG,XPS,ESI-MS等进行了表征。这是首次将所含混合价的聚氧钼酸锑用作非均相催化剂,可有效地在以下条件下催化有机硅烷氧化为硅烷醇反应条件温和。此外,该催化剂稳定并且在三个反应循环后保持其催化活性。
