Abstract
Imidazolium based ionic liquid catalyzed an efficient synthesis of N2-arylbenzylidenyl isonicotinic acid hydrazide derivatives under reflux condition. This protocol offers several advantages including high yields of pure Schiff base products in short reaction time and easy experimental work-up procedure. Ionic liquid can be recovered and reused up to four cycles without loss of catalytic activity.
