Abstract

ZnO nanoparticles as efficient and reusable catalyst for the synthesis of 2H- indazolo[2,1-b]phthalazine-triones from the one-pot, four-component reaction of arylaldehydes, hydrazine monohydrate, phthalic anhydride, dimedone under solvent-free conditions with short reaction times is described. The ZnO nanoparticles can be reused several times without significant loss of its catalytic activities.
