Potassium Fluoride on Alumina: Dry Condensation of 3-Phenylisoxazol-5-one with Aldehydes Under Microwave Irradiation

Abstract
3-Phenylisoxazol-5-one (2) and aromatic aldehydes were condensed to 3-phenyl-(4-arylmethylene) isoxazol-5-one (3) in the presence of Al2O3-KF without solvent under microwave irradiation.
