Kinetics of the diels-alder reaction of 2,5-dimethylfuran with <i>N</i>-phenylmaleimide: high hydrostatic pressure, temperature, and solvent effects

Abstract

The rate constants of the Diels-Alder reaction of 2,5-dimethylfuran (1) with N -phenylmaleimide (2) in 5 solvents in the range of temperature 25-45°C and pressure 1-1000 bar have been determined. Activation enthalpy, entropy, Gibbs free energy and volume parameters have been calculated. The equilibrium constants of the 1 + 2 reaction in benzene in the temperature range 25-55°C have been determined, and the reaction enthalpy and entropy have been calculated.
