Ferric sulfate hydrate [Fe2(SO4)3·xH2O], Three component reactions, Phthalhydrazide, Cyclic-1,3-diketones, 2H-Indazolo[2,1-b] phthalazine-trione derivatives
Hydrated ferric sulfate can be used as an efficient and reusable catalyst for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives via one-pot three-component condensation reaction of phthalhydrazide, aromatic aldehydes and cyclic-1,3-diketones in ethanol under reflux conditions.
