| Popis: | A variable temperature magnetic resonance study of π-C5H5M(CO)2LH complexes, shows the existence of intramolecular exchange between two isomers. Kinetic data have been obtained by line-shape analysis for rates of isomerisation with the Kubo—Sack matrix method, and thermodynamic data have been established. The structure of the transition state is discussed. Starting from these, special attention has been given to determine the steric influence of bulky groups in various phosphines. |
