Deskripsi
The nitrosation of 1<i>H</i>-1-alkyl-6-methyl-3-phenylpyrazolo[5,1-c][1,2,4]triazoles leads to new 1<i>H</i>-1-alkyl-6-methyl-7-nitroso-3-phenylpyrazolo[5,1-c][1,2,4] triazoles that react in acidic media, giving rise to 1<i>H</i>-1-alkyl-7-hydroxyimino-6-methyl-3-phenylpyrazolo[5,1-c][1,2,4]triazolium salts. These compounds were characterized by FT-IR, UV-Vis, <sup>1</sup>H-NMR, <sup>13</sup>C-NMR, and <sup>15</sup>N-NMR spectroscopic techniques.
