The reactions of 1,4-diazabutadienes with HClO₄ were studied in detail. The final products obtained were not the hydroperchlorates of but imidazolium perchlorates or . A possible reaction process is postulated on the basis of the isolation of the pan class="TH_term4">intermediatepan> 2-iminomethylimidazolium salt . The factors influencing the conversion of to the imidazolium perchlorates and were discussed with regard to the electronic and steric effects of the N-substituents. This reaction can serve as an approach for the synthesis of imidazolium derivatives.
