Abstract

Abstract Neat non-volatile amines react with various aromatic aldehydes in the absence of any catalyst, solid support, or solvent, to give imines after a reaction time of eight minutes under microwave irradiation by a clean and very efficient process (yields: 75-100%). In the case of volatile amine, methylamine, 1, 3-dimethylurea dispersed on montmorillonite K10 is used as an amine precursor to prepare the corresponding imines.
