The potential application of an efficient, easily recoverable and reusable magnetically separable FeNi 3 /KCC-1/APTPOSS nanoparticle-supported Cu(II) cyclam and salen complex catalyst for the synthesis of tetramethylquinoline-2,4-diamine was investigated. The FeNi 3 /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⋅PF 6 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.
A series of novel disulfonamide derivatives were synthesized and characterized by FT-IR, 1 H NMR and MS techniques. In order to prepare new disulfonamides, at first we synthesized new diamines containing a pyridine ring. Then, they have been reacted with sulfonyl chlorides to give corresponding disulfonamides.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
