Heating 6-aryl-1,5-diazabicyclo[3.1.0]hexanes in the presence of aryl isocyanates or aryl isothiocyanates leads to the formation of the corresponding 2,3-diarylperhydropyrazolo[1,2-a][1,2,4]triazol-1-one or 2,3-diarylperhydropyrazolo[1,2-a][1,2,4]triazol-1-thione in good yield as a result of 1,3-dipolar cycloaddition of isocyanate (isothiocyanate) to an initially formed ylide.
