- N-NITROHYDRAZINES AND THEIR SALTS
-
A method was developed for the synthesis of functionally substituted N-nitrohydrazines by nonacid nitration of the respective silylhydrazines.It was shown that the stability of these compounds increases with increase in the number of electronegative substituents.The first representative of N,N'-dinitrohydrazines, i.e., N,N'-dinitro-N,N'-diacetylhydrazine, was synthesized.Some of the obtained N-nitrohydrazines are characterized by dissociation with the formation of diazenes.The action of nucleophilic reagents on functionally N,N'-disubstituted N-methyl-N'-nitrohydrazines gave the salts of N-nitrohydrazines.

- Methoxy- and Aminoisocyanate
-
Methoxyisocyanate (1) can be prepared by photolysis of methyl azidoformate (3) or pyrolysis of N-methoxycarbonyl-O-methylhydroxylamine (4).Aminoisocyanate (2) is similarly formed on photolysis of carbamoyl azide (12) and pyrolysis of either methyl carbazate (13) or 3,4-diaminofurazan (14).The infrared spectra of 1 and 2 in an argon matrix at 10 K have been measured, and some of their properties are discussed. - Keywords: Flash pyrolysis/ Matrix IR spectroscopy/ Photolysis
