CuFe۲O۴ and ZrP۲O۷ nanoparticles as highly ecient catalysts for the one-pot synthesis of phthalazine derivatives under solvent-free conditions

چکیده مقاله

ZrP2O7 and CuFe2O4 nanoparticles as ecient and reusable heterogeneous catalysts have been used for the preparation of 2H-indazolo[2,1-b]phthalazine-triones and 1H-pyrazolo[1,2-b]phthalazine-diones, respectively, under solvent-free conditions in good to excellent yields and short reaction times.
