dc.description.abstract The rate of the fastest ene reaction between 4-phenyl-1,2,4-triazoline-3,5- dione (1) and 2,3-dimethyl-2-butene (2) is studied by means of stopped flow in solutions of benzene (k 2 = 55.6 ± 0.5 and 90.5 ± 1.3 L mol-1 s-1 at 23.3 and 40°C) and 1,2-dichloroethane (335 ± 9 L mol-1 s-1 at 23.5°C). The enthalpy of reaction (-139.2 ± 0.6 kJ/mol in toluene and -150.2 ± 1.4 kJ/mol in 1,2-dichloroethane) and the enthalpy (20.0 ± 0.5 kJ/mol) and entropy (144 ± 2 J mol-1 K-1) of activation are determined. A clear correlation is observed between the reaction rate and ionization potential in a series of ene reactions of 4-phenyl-1,2,4-tri-azoline- 3,5-dione with acyclic alkenes. © 2014 Pleiades Publishing, Ltd.
