A magnetically recoverable, efficient and selective copper based nanocatalyst has been synthesised via covalent grafting of 2-acetylthiophene on a silica coated magnetic nanosupport followed by metallation with copper acetate. The obtained organic-inorganic hybrid nanomaterial has been characterized by electron microscopy techniques (SEM and TEM with EDS), XRD, VSM, FT-IR and AAS. The catalytic performance of the novel nano-catalyst is evaluated in the active transformation of various aromatic amines to industrially-important alkylated amines. The nanocomposites afford high turnover frequency and high selectivity for amines under aerobic conditions. Furthermore, the heterogeneous nature of the catalyst allows easy magnetic recovery and regeneration, which makes the present protocol highly beneficial to address the industrial needs and environmental concerns. † Electronic supplementary information (ESI) available.

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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
