Et. Apasov et al., SYNTHESIS OF HETEROCYCLIC AZOXY COMPOUNDS FROM C-NITROHETEROCYCLIC COMPOUNDS AND METAL DERIVATIVES OF TERT-BUTYLAMINE, Bulletin of the Russian Academy of Sciences, Division of Chemical Sciences, 41(7), 1992, pp. 1280-1281
The reaction of 3-nitropyrazole and 3(5)-nitro-1,2,4-triazole with t-B
uNHMgBr gives the corresponding asymmetrical diazene oxides. Furthermo
re, 3(5)-(1,1-dimethylethyl)azoxy-1,2,4-triazole was also synthesized
by the reaction of 1-trimethylsilyl-3(5)-nitro-1,2,4-triazole with t-B
uNHLi.
