Synthesis and properties of 5-diazoimidazoles and imidazolyl-5-diazonium salts

Diazotization of 4-R-5-aminoimidazoles (R = CONHAr, CONHAIk, morpholinocarbonyl, or piperidinocarbonyl) with sodium nitrite in aqueous solutions of mineral acids afforded the corresponding 5-diazoimidazoles, whereas the reactions in concentrated tetrafluoroboric acid produced imidazolyl-5-diazonium salts. In the solid phase, diazonium salts are transformed into the corresponding diazo compounds.
