Synthesis of mordant azo dyes using supported diazonium ions and Bronsted acidic ionic liquids
INDIAN JOURNAL OF CHEMISTRY SECTION B-ORGANIC CHEMISTRY INCLUDING MEDICINAL CHEMISTRY（2018）
摘要
Diazonium ions supported on Amberlite IR120 (Na+) have been prepared and used for the synthesis of a variety of 5-arylazo-8-hydroxyquinoline in solid state as well as in pyridinium based ionic liquids under microwave heating. The two methods have been compared with respect to ease of recovery, yield, reaction time and environmental impact.
