Abstract
The reaction of aryl substituted 1,2,3-triazolium-1-imide 1,3-dipoles with substituted aryl isocyanates and isothiocyanates gave new ring systems based on the imidazo[4,5-c][1,2,3]triazole structure. With the isothiocyanates an apparent exchange of aryl groups between the dipole and recovered isothiocyanate dipolarophile shed light on the initial intermediate in the reaction.
