The rates of an ene reaction between 4-phenyl-1,2,4-triazoline-3,5-dione and hex-1-ene were studied in a temperature range of 15-40 °C and in a pressure range of 1-2013 bar. The enthalpy of reaction in 1,2-dichloroethane (-158.2±1.0 kJ mol-1), the enthalpy (51.3±0.5 kJ mol-1), entropy (122±2 J mol-1 K-1), and volume of activation (-31.0±1.0 cm3 mol-1), and the volume of this reaction (-26.6±0.3 cm3 mol-1) were determined. The high exothermic effect of the reaction suggests its irreversibility.

The kinetic measurements for the reaction of 4-substituted-1,2,4-triazoline-3,5-diones (4-R-TD; R=Ph, Me, p-MeOC6H4, p-NO2C6H4) with alkenes have been undertaken.The reactivity of alkenes was found to be very sensitive to substituent effects.The effects of solvent and substituent on TD were small.In the reaction of TD with ene products, side reactions as well as second-step ene reactions were observed.The reactions of 1-alkyl-4-phenyl-1,2,4-triazolidine-3,5-diones were investigated, and the reaction products were isolated.
