Аннотация: 5,6-Diaryl-2,3-dihydro-1H-pyrazolo[1,2-a]pyrazolium tetrafluoroborates (hexafluorophosphate) were unexpectedly synthesized along with expected 1,3-diaryl-2-nitrotetrahydro-1H,5H-pyrazolo[1,2-a]pyrazoles, under the action of 1-nitro-2-(3-nitrophenyl)ethylene on 6-aryl-1,5-diazabicyclo[3.1.0]hexanes in ionic liquids with the Et₂O·BF₃ catalyst, whereas the same reaction with unsubstituted β-nitrostyrene produced only 1,3-diaryl-2-nitrotetrahydro-1H,5H-pyrazolo[1,2-a]pyrazole derivatives.
