Activation of η5-Cyclopentadienyl Ligands toward Nucleophilic Attack through η5 → η3 Ring Slippage. Kinetics, Thermodynamics, and NMR Spectroscopy
摘要:
The kinetics of the reactions of the complexes [Ru(eta(5)-C5H5)(eta(4)-C5H4O)(L)]CF3SO3 (L = CH3CN, pyridine, thiourea) with PMe3 have been, studied in acetone. The novel reaction, products [Ru(eta(3)-C5H5)(eta(4)-C5H4O)(PMe3)(L)]CF3SO3 formed are fluxional in solution due to an intramolecular enantiomeric equilibrium likely proceeding through a five-coordinate eta(1)-C5H5 intermediate.
