A Cp*-Rh based D-shaped binuclear metallacycle and a template-free molecular Borromean ring (BR) were obtained in high yield using the semi-rigid thioether dipyridyl ligand 1,4-bis[(pyridin-4-ylthio)methyl]benzene (Bptmb). The topological transformation from a binuclear metallacycle and a BR to tetranuclear metallacycles was realized via the controlled oxidation of thioethers. The strategy used in this work can be regarded as a new form of stimuli-responsive post-synthesis modification (PSM).
使用半刚性硫醚二吡啶配体1,4-双[(吡啶-4-基硫基)甲基]苯（Bptmb）以高产率获得了一种基于Cp*-Rh的D形双核金属环和一种无模板分子Borromean环（BR）。通过硫醚的可控氧化实现了从双核金属环和BR到四核金属环的拓扑转变。这项工作中使用的策略可被视为刺激响应性后合成修饰（PSM）的一种新形式。
