Synthesis of Pyrazole Dyes Derivatives

Libyan Journal of Science &Technology, 2022
Eight azo dyes were prepared by diazotization of 5-amino-3 (cyanomethyl)-1H- pyrazole-4-carbonitrile in presence of sodium nitrite and hydrochloric acid at 0°C. We reported that the malononitrile molecule was a very active nucleophile, where can react with the diazonium salt of pyrazole in presence of sodium acetate and ethanol to yield corresponding ...
