摘要：
The effects of temperature, solvent nature, and high hydrostatic pressure on the rate of the ene reaction of 4-phenyl-3H-1,2,4-triazole-3,5(4H)-dione with β-pinene have been studied. The reaction gives only one product and is accompanied by a large heat effect. Comparison of the activation and reaction volumes indicates cyclic structure of the transition state. The reaction rate changes by a factor of 200 in the series of nine examined solvents, but this variation is not determined by solvent polarity.
