A new and efficient manganese-based magnetic nanocatalyst has been developed via covalent grafting of the manganese acetylacetonate complex onto amine-functionalized silica-coated iron-core nanoparticles. The obtained nanomaterials were characterized by XRD, HRTEM, VSM, EDS, ICP-OES, and FT-IR. The resulting nanocatalyst was found to be efficient for selective oxidation of organic halides and alcohols to desirable carbonyl compounds in terms of excellent yields with high turnover number. The effortless magnetic recovery of the catalyst and its reusability renders the present strategy practical to address environmental and industrial issues.
