对油酸甲酯乙烯解反应中已知的烷基化钌配合物的筛选表明，含有两个膦供体配体的grubbs型ru -催化剂对末端烯烃的形成具有很高的选择性。第二代钌催化剂几乎只促进自分解产物的形成。具有螯合烷基基的配合物（hoveyda型）通常对醇解和自分解产物都表现出较差的选择性。配合物2b和2d在催化剂负载为2ppm时促进油酸甲酯的自复分解，在高达110°C（使用2d）和高达150°C（使用2b）时没有明显的异构化。
The screening of known ruthenium alkylidene complexes in the ethenolysis of methyl oleate shows that the Grubbs-type Ru-catalysts bearing two phosphine donor ligands exhibit high selectivity for the formation of terminal olefins. Second-generation ruthenium catalysts promote almost the exclusive formation of self-metathesis products. Complexes with chelating alkylidene moieties (Hoveyda-type) generally exhibit poor selectivity for both ethenolysis and self-metathesis products. Complexes 2b and 2d promote self-metathesis of methyl oleate with catalyst loading of 2 ppm without significant isomerization up to 110 °C (using 2d) and up to 150 °C (using 2b).
