Similarly, the reaction of 4-amino-l-mcthyl-3-methylthio-l//-[l,2,4]tnazol-5(4//)-onc 116 furnishes 6-aryl-2-methyl-7//-[l,2,4]triazolo[4,3-/d[l,2,4]triazol-3(2//)-ones 117 (Equation 32) <1985BCJ735> and the 4-amino[l,2,4]triazole-5(4//)-thione 118 furnishes 6-aryl-l,3-dimethyl-l//-[l,2,4]triazolo[4,3-3][l,2,4]triazoles 119 (Equation 33)... 

There has been some interest in the chemistry of aminonitroazoles when used as high energetic compounds. Data concerning direct introduction of the amino group into the nitroazole cycle have been absent in the literature till the present time. We have studied the vicarious nucleophilic substitution of l-methyl-4-nitropyrazole and also l-mcthyl-4-nitroimidazole (Table 3.10), 4-nitro-2-phenyl-1,2,3-triazole (Table 3.24), and nitrobenzimidazoles (Table 3.25) under the effect of 1,1,1-trim-ethylhydrazinium halides and 4-amino-1,2,4-triazole by NMR spectroscopy (DMSO-<76) (Scheme 3.5) [220, 272-278] ...

The cycloadditions of 4-mcthyl-3//-1,2,4-triazole-3,5(4//)-dione to tricyclo[5.2.2.02 6]-undeca-2,5,8-triene 37, tetracyclo[5.3.2.02,6.08 1°]dodeca-2,5,ll-triene, and -2,5-diene 39 have been examined107,115. Complete diastereoselectivity was observed only for the trienc derivatives 37 the structure of the adducts 38 was determined by X-ray.
