Reaction Steps

Primary aromatic amines also have been diazotized in solvents by means of pure nitrogen tetroxide. O. N. Witt, Tagbl. Natf.-Vers. Baden-Baden 1879, 194 (Chem. Zentr. 1880, II, 226) reported obtaining benzenediazonium nitrate by the reaction of anhydrous pure nitrogen tetroxide with aniline in an anhydrous benzene solution; and B. Houston et al., J. Am. Chem. Soc. 47, 3011-3018 (1925), obtained a diazoaminobenzene derivative as well as the corresponding diazonium nitrate by the action of pure, anhydrous nitrogen tetroxide on o-, m-, and p-nitroaniline in an anhydrous benzene solution.
