Derivatives of N-?-nitroalkylhydrazines 3. Reaction of N-trinitromethylhydrazines with piperidine and pyridine

Abstract

1. Dinitroformaldehyde alkoxycarbonylhydrazones and pyridinium nitronate betaines were obtained for the first time. 2. The dinitroformaldehyde alkoxycarbonylhydrazones readily replace the nitro group by a halogen atom when treated with dry hydrogen chloride in ether or with potassium chloride in DMFA. 3. The ionization constants of the dinitro and chloronitroformaldehyde alkoxycarbonylhydrazones in water were determined.
