Abstract

Coumarins occupy an important place in the realm of natural products and synthetic organic chemistry. A highly efficient green process for synthesis of 3-Phenyl Coumarin from salicylaldehyde and phenyl acetyl chloride in presence of N-methyl imidazole is developed. The method is simple giving high yield of pure product. The N-methyl imidazole form N-methyl imidazole hydrochloride which can be deprotonated to get N-methyl imidazole which can be recycled for the next reaction of 3-Phenyl Coumarin .N-methyl imidazole hydrochloride is also useful ionic liquid. This method also applies to ultrasonic bath to synthesis of same molecule and some other derivatives. Due to the recycle of reagents the process is green.
