Dendrimer templated ionic liquid nanomagnetic for efficient coupling reactions.

In this research, a logical strategy with a recyclable synthetic perspective of view and a rational design to prepare a nanocatalyst with a dendrimer template containing ionic liquid is presented. Magnetic silica nanoparticles were prepared using the Stober method. Their surface was modified with the help of cyanuric chloride, melamine, and 1-methylimidazole as Linkers. Finally, the nanocatalyst was decorated with affordable copper metal. The dendrimer-templated nanocatalyst was identified by different analyses, such as FT-IR, SEM, TEM, XRD, EDX, TGA, CHN, and ICP-OES. FeO@SiO@NTMP-IL-Cu was used as a heterogeneous nanocatalyst with good performance and reusable in coupling syntheses. The synthesis of A-coupling and Ullmann coupling was performed under solvent-free and THF conditions, respectively, with high yields. Reusability and high efficiency of products in the vicinity of this catalyst, the use of cheap and available metal are desirable features of this synthetic catalyst.
