Abstract

ABSTRACT A quick and solvent-free approach involving the exposure of neat reactants to microwave irradiation in conjunction with the use of clinoptilolite, H 3 PW 12 O 40 and Fe 2 O 3 nanoparticle catalysts is described. In this work, condensation of hydroxylamine hydrochloride, sodium acetate, acetoacetic or benzoyl acetic ethyl ester and appropriate aldehydes by employing catalysts gave 5 (4H)-isoxazolone only in one step. Catalyst ...
