A green and one-pot synthesis of 1H-pyrazolo(1,2-b)phthalazine-5,10-dione derivatives by facil route at 100℃ under solvent-free condition by nanostructure cu-doped zno hollow sphere as novel and recyclable catalyst is reported. The main benefits of this method are high product yield, exprimental simplicity and use of the nonpoisonous catalyst.
