Syntheses and structures of magnetic nanodendrimers and their catalytic application in organic synthesis

Abstract

Magnetic nanoparticles have been proved as a tremendously powerful synthetic tool to achieve a milder process for the organic transformations and also suggested many potentialities in biomedical applications. They have an important role in the human health, environment protection, and energy resource management. Excellent reusability, easy separation of nanosized catalysts, and stability are the significant advantages of these catalysts. Hence, detailed studies on their synthesis mechanism for both chemical transformations and biomedical applications are crucial. In this review, we described a brief introduction of the dendrimers and various methods that are used for their synthesis, followed by the discussion of the syntheses and structures of magnetic nanodendrimers and their catalytic application in organic synthesis. We accordingly embarked on the studies on their synthesis mechanism for chemical transformations especially their surface modification since 2001.

Copper nanoparticles supported on magnetic functionalized chicken feather‐derived activated carbon/metal–organic frameworks nanocomposite: As an efficient adsorbent for the removal of methylene blue and a unique heterogeneous catalyst for the synthesis of tetrahydrobenzo[b]pyran derivatives

“…The easy recovery and reusability of the heterogeneous catalysts is a substantial advantage that makes them attractive in a variety of industrial applications 57 . The reusability of the Fe 3 O 4 @CFC‐COOH@TMU‐16@Cu was evaluated in the model reaction under the best‐obtained reaction conditions.…”

A slight decrease in the percentage yields of regenerated catalyst is observed in each run, which indicates the reusability of Fe 3 O 4 @CFC-COOH@TMU-16@Cu after six runs (Figure 10).…”

Synthesis and Studies of Pyridoneimine-Functionalized PETIM Dendrimers

“…Encapsulated magnetic nanoparticles (NPs) act as a nanocarrier for drug molecules due to the presence of multiple functional groups . Besides biological applications, magnetic nanodendrimers find immense utility in various organic catalysis . Thus, applications of dendrimers in disparate studies illustrate the accrued benefits resulting from their highly branched structures.…”

Schiff base Mo(vi) complexes grafted on Merrifield resin as recyclable and efficient catalysts for the synthesis of pyrrole-2-ones

“…Nitrogen-containing heterocycles show good anticancer activity. [1][2][3] Among them, pyrrole-2-ones are a class of pyrrolidine compounds with a five membered lactam ring. They exist widely as building blocks in natural products and various synthetic compounds.…”
