Abstract
Abstract An efficient and facile synthesis of hydrazones, bis (indolyl) methanes and bis (4- hydroxycoumarin) methanes is facilitated by room temperature ionic liquid choline chloride– oxalic acid (ChCl: Ox). ChCl: Ox (10 mol%) efficiently catalyzes condensation of aldehydes with phenylhydrazine giving corresponding hydrazones in high yield (92–96%) within short reaction time of 3–5 min. Electrophilic cyclization reaction of indole and 4-hydroxy ...
