complex catalyst for the synthesis of tetramethylquinoline‐2,4‐diamine was investigated. The FeNi3/KCC‐1/APTPOSS/Cyclam@Salen/Cu(II) magnetic nanoparticles were thoroughly characterized using various techniques. This catalyst was utilized in the direct and selective chemical reaction of 1,3‐dichlorovinamidinium⋅PF6 with aniline for the synthesis of tetramethylquinoline‐2,4‐diamine. The recycled catalyst
