Nitrotriazoles and Nitrotetrazoles

The analogical fragmentation way shows the isomeric 1-chloro- and 5-chloro-3-nitro-l,2,4-triazoles herewith that the isomers have some differences. 5-Chloro 

Probably technical possibilities of method in those times have not allowed determining all peaks of these compounds (Tables 3.74 and 3.75). 

Mass spectrum of l-nitro-l,2,4-triazol-5-one has only two intensive peaks with mass m/z 101 [M-30+l]+ and m/z 85 [M-46t-l]+ corresponding NO and N02 [611]. 

The alkylation products of A -chloro-3-nitro-l,2,4-triazole [580], heterylation products of nitrotriazoles [612], glycosylation products of 3-bromo-5-nitro-l,2, 

4- triazole, 2,4-dinitroimidazole and 3-nitro-l,2,4-triazolon-5 [402] were identified by mass spectrometry.
