Meghasham N. Narule* & Vibha M. Nikose
ABSTRACT
A rapid sonochemical synthesis of 2-imino imidazoles using solvent and catalyst 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM][BF4]. The overall merits of this reaction are faster rates, milder conditions, higher yields, shorter time and facile workup. The simplicity of the reaction facilitates the delineation of a green chemistry methodology: use of designer solvent as catalyst and ultrasound irradiation, to define useful protocol for optimal conversions.
Keywords: Ultrasonic irradiation, [BMIM][BF4] ionic liquid, 2-imino imidazole.
