茚满酮()处理[Cp * RuCl](4),得到Cp * Ru(Cl)(kappa(2)-P,O-)(),分离产率为96%。在N(2)气氛下进行脱卤化氢作用提供了双核复合物(分离产率为78%),该复合物由两个配位不饱和的Cp * Ru(kappa(2)-P,O)片段()通过末端连接而组成配位的微N(2)
配体。尽管尚未直接观察到复杂的化合物,但反应性研究表明,该化合物可以作为方便的来源。暴露于CO(93%的收率)或两当量的PhCN(91%的收率)气氛中,可制得可分离的加合物。暴露于H(2)气氛中可提供加合物。(sigma-H(2))()定量;撤离并重新引入N(2)气氛后,会干净地转换回N。用两当量的PhSiH(3)或Ph(2)SiH(2)处理可得到具有(H)(2)Ru-SiPhX-O片段的产物(分别为和;分离产率均为95%),对应于净双双有机
