A cost-effective and green aqueous synthesis of 3-substituted coumarins catalyzed by potassium phthalimide

A cost-effective and green aqueous synthesis of 3-substituted coumarins catalyzed by potassium phthalimide

An efficient procedure for the synthesis of various 2-imino-2H-chromene-3-carbonitriles, 2-oxo-2H-chromene-3-carbonitriles as well as 2-oxo-2H-chromene-3-carboxylic acids is reported. It has been found that potassium phthalimide (PPI) catalyse the Knoevenagel condensation reaction of salicylaldehyde...
