| 摘 要： | 采用＾５１Ｖ ＮＭＲ监测在核磁管内模拟（ＮＨ４）３ＶＳ４／Ｅｔ４ＮＢｒ／ＣｕＢｒ／ＰＰｈ３体系在ＣＨ２Ｃｌ２中的反应过程，研究了反应条件如反应物不同配比对生成各种〖ＶＳ４－Ｃｕｎ〗（ｎ≤６）簇合物的影响，提供了该反应体系在ＣＨ２ＣＩ２溶液部成簇过程的一些信息。该方法不仅可用来研究反应机理，而且可用于地一些条件难以确定（溶剂、温度、酸碱度等）的簇合物如低核数及更高核数Ｖ－Ｃｕ－Ｓ簇合物的合成。

| Abstract: | 51V NMR was used as a new pseudo in situ and nondestructive analytical tool to monitor and identify possible products of [VS4-Cun] (n≤6) clusters. The reaction of (NH 4) 3VS 4/Et 4NBr/CuBr/PPh 3 systems with various molar ratios in CH2Cl2 were mimicked in NMR tubes. The reaction conditions for the formation of the [VS 4-Cu n] clusters with different coordinate number of copper atoms n were studied. The results show the influence of the ratio among the reactants on the products and reveal the reaction mechanism in solution. This method not only provides some information about reaction mechanism, but also provides a guide in the synthesis of some clusters such as V-Cu-S clusters with less or more coordinate copper number whose reaction conditions (solvent, temperature, pH etc.) are difficult to be determined. |
