The catalytic performances of three Phosphabicyclononane (Phoban)-containing ruthenium-based pre-catalysts have been evaluated for metathesis transformations. A wide screening of substrates in ring-closing metathesis reactions reveals the greater efficiency of pre-catalyst 4. Comparison of the catalytic activities of 4 with Grubbs' first-generation pre-catalyst illustrates the key role of the Phoban ligand. Additionally, a comparative study of three Phoban-containing pre-catalysts has been conducted for the self-metathesis of 1-octene at low catalyst loading (25-100 ppm).
已对三种含磷双环壬烷（Phoban）的钌基预催化剂在复分解反应中的催化性能进行了评估。在关环复分解反应中对多种底物进行的广泛筛选表明预催化剂4具有更高的效率。将4的催化活性与格拉布第一代预催化剂进行比较，说明了Phoban配体的关键作用。此外，还对三种含Phoban的预催化剂在低催化剂负载量（25 - 100 ppm）下1 - 辛烯的自复分解反应进行了对比研究。
