5-Nitrofurfuryl trichloromethyl sulphone (I) was reacted with paraformaldehyde in methanol in the presence of piperidine as catalyst to give 1-(5-nitro-2-furyl)-1-trichloromethylsulphonyl-2-(5-nitro-2-furyl)cyclopropane. This substance was also obtained from 1-(5-nitro-2-furyl)-1-trichloromethylsulphonyl-2-(5-nitro-2-furyl)ethylene and diazomethane. The reaction products were characterized by IR, UV, 1H NMR and mass spectral data.
