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

Abstract

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.

Chitosan nanoparticles functionalized poly‐2‐hydroxyaniline supported CuO nanoparticles: An efficient heterogeneous and recyclable nanocatalyst for N‐arylation of amines with phenylboronic acid at ambient temperature

“…[73] After assembling CuO NPs on the P2-HA-CSN, the peaks at 600-800 cm À1 shifted to the higher wavelength region, indicating the interactions between CuO and 2-HA, which are happened through π-π* of quinoid rings and required less energy (Figure 5c). [61] Infrared (IR) results confirm the successful synthesis of CuONPs-P2-HA-CSN nanocatalyst. Further studies on the recoverability of CuONPs-P2-HA-CSN nanocatalyst were carried out by recording the FT-IR spectrum of the recovered catalyst (Figure 5d).…”

“…[58] In a few studies, the PANI with its imaginary properties such as thermal, electrical, and catalytic properties was combined with the CS and applied as a support for catalytic applications. [59,60] Herein, in continuing our research on the application of heterogeneous catalysts in organic reactions, [61][62][63] the CuONPs-P2-HA-CSN nanocatalyst was designed and synthesized to apply in the Chan-Lam cross-coupling reaction of amine and phenylboronic. In this design, poly (2-hydroxyaniline) (P2-HA), as a conducting polymer, was grafted to the CSN in a straightforward method to synthesize P2-HA-CSN.…”

Functionalized Silicas for Metal‐Free and Metal‐Based Catalytic Applications: A Review in Perspective of Green Chemistry

“…With the use of 4‐aminoethylpiperidine during the sequential alkylations with cyanuric chloride, the grafting of organic dendrite molecules on silica is achieved . Sodium chloroacetate has been also used for the N‐alkylation with aromatic FS Different to the above reports, research group of S. M. Sadeghzadeh has carried out the nucleophilic substitution on eight chlorine sites of chloropropyloctasilsesquioxane using APTES and successively, the obtained product is anchored on silica …”

“…In the other method, the functional groups of already prepared complexes form the chemical bond with the functional groups of FS and no direct chemical interaction between the metal centres and functional groups of FS is expected . Very differently, M. Halder et al.…”
