合成了一系列由两个三原子桥连接的三芳基帽组成的环环烷。桥头官能团包括与胺,氢硅烷,甲基硅烷和乙氧基硅烷结合的膦。计算研究准确地预测,当桥头取代基较小时(孤对或质子),强烈建议在桥头立体化学中使用in ,in,但较大的桥头取代基则有利于in in ,out立体异构体的形成。讨论了这些化合物的X射线结构,光谱和反应性,以及其中一种环烷拆分为纯对映体的方法。
Two dinuclear oxovanadium(IV) thiolate complexes, [N(C5H11)4]2[VOL1]2 (1) and [N(C4H9)4][(VOL2)2(mu-OCH3)] (2) (where L1 = [(CH3)SiO(C6H4-2-S)2]3- and L2 = [(C6H5)PO(C6H4-2-S)2]2-), have been synthesized and characterized. The geometry of the anion in 1 can be classified to an edge-sharing bi-square-pyramid with a syn-orthogonal configuration. The one in 2 can be view as a face-sharing bioctahedron
