配合物[RuCl（η6-C10 H14）{κ3（P，C，C）-Ph 2 PCH 2CH = CH 2}][BPh 4]（2）发生亲核攻击，根据亲核试剂和反应条件，攻击金属或配位烯烃。膦在配位烯烃上的亲核攻击导致非对映选择性地得到作为对映体RRuSc/SRuRC的外消旋混合物的带有κ2（P，C）-配体的络合物[RuCl（η6-C10 H14）{RRu 2（P，C）-Ph 2 PCH 2CH（PR 3）CH 2}]+。这些动力学稳定的异构体经历异构化过程，导致分离出作为非对映异构体RRuRC/SRuSC的化学稳定的产物。已经对异构化过程进行了31 P {1 H} NMR监测实验。
Nucleophilic attack on complex [RuCl(η6‐C10H14){κ3(P,C,C)‐Ph2PCH2CH=CH2}][BPh4] (2) takes place, either to the metal or to the coordinated olefin depending on the nucleophile and the reaction conditions. The nucleophilic attack of phosphanes on the coordinated olefin leads diastereoselectively to complexes [RuCl(η6‐C10H14){ĸ2(P,C)‐Ph2PCH2CH(PR3)CH2}]+bearing κ2(P,C)‐ligands obtained as a racemic mixture of the enantiomersRRuSc/SRuRC. These kinetically stable isomers, undergo an isomerization process leading to the thermodynamically stable products isolated as the diastereoisomerRRuRC/SRuSC.31P{1H} NMR monitoring experiments on the isomerization processes have been carried out.
