A green protocol has been developed for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones by one-pot cyclocondensation reaction of phthalhydrazide, aromatic aldehydes, and malononitrile or ethyl cyanoacetate using sulfonic acid functionalized SBA-15 (SBA-Pr-SO3H) as a heterogeneous solid acid catalyst under solvent-free conditions.
