The reaction of N-phenyltriazolinedione with three simple alkyl-substituted alkenes in water/alcohol or water/acetone solution was found to give a mixture of the corresponding ene and water addition products. The new hydration products were characterized by spectroscopy, and in one case, also by X-ray diffraction analysis. Thermodynamic parameters were determined for the reactions involving 2-methylbut-2-ene

Solvent effect in pericyclic reactions. IX. The ene reaction.
The solvent effect on the ene reactions of diethylazodicarboxylate and triazolindione was determined in 18 and 16 solvents respectively. The first enophile gives a solvent effect that depends on solvent acidity (type a solvent effect), while in the second reaction the significant solvent effect is the result of the nucleophilic character of the solvent (type b solvent effect). These are the same solvent behaviours observed in the analogous Diels-Alder cycloadditions, and evidence of the close parallel between these two pericyclic reactions was produced by determining the effect of inorganic perchlorates on their rates.
