Add to ORKG843-851An efficient and convenient zinc acetate dihydrate (Zn(OAc)2.2H2O) catalyzed synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been accomplished via one-pot four-condensation of phthalic anhydride, hydrazine monohydrate, aromatic aldehydes derivatives and malononitrile under solvent-free conditions. The notable advantages of the present procedure are: operational simplicity, eco-friendly, environmentally benign nature, low-cost and non-toxic catalyst, no necessity of chromatographic purification steps, short reaction times and good to high yields
