研究了络合物[Ru(η5-C5H5)(η4-C5H4O)(L)]CF3SO3 （L = CH3CN、吡啶、硫脲）与PMe3在丙酮中反应的动力学。新型反应产物[Ru(η - 3- c5h5)(η - 4- c5h4o)(PMe3)(L)]CF3SO3在溶液中是流动的，这是由于分子内的对映体平衡可能是通过五坐标的η - 1- c5h5中间体进行的。
The kinetics of the reactions of the complexes [Ru(η5-C5H5)(η4-C5H4O)(L)]CF3SO3 (L = CH3CN, pyridine, thiourea) with PMe3 have been studied in acetone. The novel reaction products [Ru(η3-C5H5)(η4-C5H4O)(PMe3)(L)]CF3SO3 formed are fluxional in solution due to an intramolecular enantiomeric equilibrium likely proceeding through a five-coordinate η1-C5H5 intermediate.
