The reaction of triisopropyl phosphite with phosphine-based indenylidene pre-catalysts affords "1(st) generation" cis-complexes. These have been used in olefin metathesis reactions. The cis-Ru species exhibit noticeable differences with the trans-Ru parent complexes in terms of structure, thermal stability and reactivity. Experimental data underline the importance of synergistic effects between phosphites and L-type ligands.

亚磷酸三异丙酯与基于膦的亚茚基预催化剂反应生成“第一代”顺式配合物。这些配合物已用于烯烃复分解反应。顺式钌物种在结构、热稳定性和反应性方面与反式钌母体配合物存在显著差异。实验数据强调了亚磷酸酯与L型配体之间协同效应的重要性。
