Green synthesis of dipyrromethanes in aqueous media catalyzed by SO3H-functionalized ionic liquid

Author affiliations

Abstract

A mild, efficient and metal-free method was described for the green synthesis of dipyrromethanes from aldehydes and unsubstituted pyrrole catalyzed by SO3H-functionalized ionic liquids (SO3H-ILs) in aqueous media at room temperature. Notably, SO3H-ILs, 1-butylsulfonic-3-methylimidazolium hydrogen sulfate ([bsmim][HSO4]) was the most efficient catalyst for moderate to good yields of the corresponding desired products.
