双核钌配合物，与桥接的碳化物和氢化物配体，和甲基三环己基氯化鏻的烯烃复分解催化剂，（IMesH2）（PCy3）（Cl）2RuCH2的热分解的结果。参与分解的离解膦提出。双核配合物具有催化烯烃异构化活性，其可负责某些烯烃复分解反应中的竞争异构化过程。
Dinuclear ruthenium complex, with a bridging carbide and a hydride ligand, and methyltricyclohexylphosphonium chloride result from thermal decomposition of olefin metathesis catalyst, (IMesH2)(PCy3)(Cl)2RuCH2. Involvement of dissociated phosphine in the decomposition is proposed. The dinuclear complex has catalytic olefin isomerization activity, which can be responsible for competing isomerization processes in certain olefin metathesis reactions.
