文摘

Different 1,4-dioxo-3,4-dihydrophthalazine-2(1H)-carboxamide and -carbothioamide derivatives were synthesized in a simple and environmentally benign method from the reaction of different phthalic anhydrides with semicarbazide or thiosemicarbazide using montmorillonite KSF clay as solid acidic catalyst and microwave irradiations under the solvent-free conditions in good yields and short reaction times.
