Recent Advances in Porphyrin‐Based Magnetic Nanocomposites: Preparation, Characterization, and Catalytic Application in the Epoxidation of Olefins

ABSTRACT Catalytic oxidation of olefins is a vital class of reaction that has drawn huge interest in both academic and industrial research due to the production of diverse important chemical intermediates. Epoxides are well known as one of the most important intermediates, and they have a notable role in different chemical and biological reactions, such as the production of amino alcohols, ethylene glycol, and resin. Due to the advantages of porphyrins, such as nontoxicity, high adaptability, and diverse characteristics, this type of bioinspired macromolecule has attracted a lot of attention in a wide range of fields. Using metalloporphyrin (MP)‐based nanohybrids as reusable catalysts for olefin oxidation provides a milder and more selective process, making it a greener substitute compared to previous approaches. Magnetic s are widely used as a perfect catalyst support in the design of new, efficient heterogeneous catalysts. Utilizing magnetic nanocatalysts with reusable features is in line with the goals of sustainable chemistry perspectives. This review summarizes the strategies of preparation, characterizations, catalytic efficiency, and plausible mechanisms of MP‐based magnetic nanocatalysts focused on the oxidation of olefins during 2013–2024.
