摘要：

The reaction of Ru3(CO)12 with C5Ph5Br yields Ru(η5-C5Ph5)(CO)2Br (1), which reacts with phosphorus donor ligands to give Ru(η5-C5Ph5)(CO)LBr (2: L = PPh3; 3: L = P(OMe)3; 4: L = P(OPh)3). A limited kinetic study has revealed that these carbonyl replacement reactions occur via a dissociative mechanism at a rate significantly faster than those for Ru(Cp′)(CO)2Br (Cp′ = C5H5 or C5Me4Et). The crystal structure of 2 is reported, and reveals that the triphenylphosphine ligand extends into the region occupied by the pentaphenyl propeller, forcing this propeller into an unsymmetrical chiral array. This chiral array complexed to a chiral ruthenium atom gives rise to diastereoisomers which can be seen in the 13C and 31P NMR spectra of 2. © 1990.
