In this literature, the synthesis of indeno[1,2‐b]indolone from starting materials of ninhydrin, derivatives of aniline, and dimedone by using copper ferrite anchored to chitosan bearing Schiff base (CuFe2O4@CS‐SB) as a catalyst in water solvent under ultrasound irradiation was described. This catalyst was designed, fabricated, and characterized by the FT‐IR, 1H NMR, XRD, SEM, TGA, mapping scan, EDX, and BET techniques. This prepared acidic, effective heterogeneous catalyst catalyzed green synthesis of indeno‐indolone derivatives in a very short reaction times between 1 and 7 min with excellent yields between 95% and 99%. Also, the FT‐IR, 1H NMR, and melting point analyses are used to identify the synthesis of the indolones as organic products.
