Solvent effects on the activation volume of a Diels-Alder reaction
Abstract
The kinetics of the isoprene+maleic anhydride reaction have been studied in various solvents at pressures up to 1400 atm. The solvent effect on the activation volumes and energies at 35°C are reported. It is shown how the solvent effect on activation volumes is useful both for mechanistic interpretation as well as for determination of the dipole moment of the transition state.
