A copper(ii) complex containing pyridine-2-carbaldehyde and its direct binding onto ethylenediamine functionalized with Fe₃O₄@SiO₂ nanoparticles for catalytic applications

Abstract

In this study, Cu(ii)-Schiff base-(CH2)3-SiO2@Fe3O4 as a novel and heterogeneous magnetic nanocatalyst was designed, synthesized and used for the synthesis of pyran derivatives and 2-benzylidenemalononitrile derivatives under mild conditions.

An immobilized Schiff base–Mn complex as a hybrid magnetic nanocatalyst for green synthesis of biologically active [4,3-d]pyrido[1,2-a]pyrimidin-6-ones

“…[16][17][18] There have been numerous studies on the graing and immobilization of metal complexes onto magnetic nanosized inorganic supports, demonstrating signicant benets in terms of enhanced catalytic activity and stability. [19][20][21][22][23][24][25][26][27] Supported metal complexes offer the advantage of easy separation from reaction mixtures using an external magnetic eld, making them highly efficient and practical for catalytic applications. Furthermore, immobilizing metal complexes on inorganic supports can improve their catalytic performance by creating a stable environment for active sites, leading to improved selectivity and reusability.…”
