Synthesis of tetramethylquinoline-2,4-diamine using FeNi3/KCC-1/APTPOSS-supported copper cyclam and salen complex as a reusable catalyst

摘要

The potential application of an efficient, easily recoverable and reusable magnetically separable FeNi3/KCC-1/APTPOSS nanoparticle-supported Cu(II) cyclam and salen 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 was analysed using inductively coupled plasma mass spectrometry, which showed only minor changes in the morphology after the reaction, thus confirming the robustness of the catalyst.
