Abstract
A procedure was developed for the preparation of 1-amino-1,2,4-triazolium 4 nitroimides by amination of triethylammonium salts of 4-nitramino-1,2,4-triazoles with O-picrylhydroxylamine. The resulting nitroimides reacted with electrophilic reagents (acyl chlorides, aldehydes, phenyl isocyanate, NO2BF4, etc.) at the amino group.
