diazo

• “By the action of nitrous acid upon the salts of the primary organic amines the so-called diazo compounds are formed.”

• “By the action of nitrous acid upon amido-azo bodies a group of bodies called diazo-azo compounds are obtained which contain the group N: N twice over, thus: --”

• “When these amido bodies are treated with sodium nitrite and hydrochloric acid they undergo a chemical change, the feature of which is that the nitrogen atoms present in the amido compound and in the nitrite unite together and a new compound is produced which is called a diazo compound, and the operation is called "diazotisation".”

• “(This allows the diazo groups to covalently couple to the tyrosine phenolic groups on the enzyme)”

• “München, where I found by a simple crystallograpic experiment the molecular weight and probable steroid nature of ecdysone which Hoppe and I later elucidated in atomic detail after my thesis work which was on the crystal structure of a diazo compound (1963).”

  Robert Huber - Autobiography

• “There have long been films impregnated with diazo dyes which form a picture without development, so that it is already there as soon as the camera has been operated.”

  As We May Think

• “Mention should also be made of his other investigations; the conversion of chloral into dichloroacetic acid, the series of studies on the amide chlorides, imide chlorides, amidines, glyoxalines, etc., his work on azo dyes and diazo compounds, and many others.”

  Otto Wallach - Biography

• “Among these were fifty on ketenes, also works on oxalyl chloride, autoxidation, aliphatic diazo-compounds, explosions, insecticides, synthetic pepper and coffee aroma.”

  Hermann Staudinger - Biography

• “_ -- The diazo-amines, R·N: N·NHR_1, are obtained by the action of primary amines on diazonium salts; by the action of nitrous acid on a free primary amine, an iso-diazohydroxide being formed as an intermediate product which then condenses with the amine; and by the action of nitrosamines on primary amines.”

• “Noelting and E. Grandmougin (_Berichte_, 1891, 24, p. 2546) obtained azoimide from dinitraniline, C_6H_3 (NO_2) _2·NH_2, by diazotization and conversion of the diazo compound into the perbromide,”
