Solvent-free syntheses of salicylaldimines assisted by microwave irradiation
A microwave-assisted condensation of salicylaldehyde and aryl amines without solvent were efficiently performed to form a series of salicylaldimines in high yields, which were confirmed by IR, 1H NMR, 13C NMR and elemental analyses. The microwave-assisted condensation provided a convenient environmental-friendship methodology for syntheses of Schiff-base in organic syntheses.
