“…The recyclable nanocatalysts presented excellent activity for the reduction of aromatic nitro compounds under mild conditions using isopropyl alcohol as a hydrogen donor. Choi and co-workers stabilized Pd nanocatalysts on magnetic core-shell nanostructures to prevent them from sintering and coagulation [68]. The magnetic core could be readily utilized for the easy recovery and recycling of the nanocatalysts.…”

This review is focused on the strategies and designs of magnetic nanostructured catalysts showing the enhanced and sustainable catalytic performances for the heterogeneous reduction of nitoaromatics. Magnetic catalysts have the benefits of easy recovery and reuse after the completion of the reactions and green chemical processes. Magnetic separation, among the various procedures for removing catalysts, not only obviates the requirement of catalyst filtration or centrifugation after the completion of reactions, but also provides a practical technique for recycling the magnetized nanostructured catalysts. Consequently, discussions will address the methodologies and exemplars for the reusable magnetic composite catalysts. Because the synthesis of ideal magnetic nanostructured catalysts is of primary importance in the development of high-quality sustainable processes, the designs, preparation methods and recyclability of various recoverable magnetic nanostructured catalysts are emphasized. The representative methods and strategies for the synthesis of durable and reusable magnetic nanostructured catalysts are highlighted. The advantages, disadvantages, recyclability and the efficiency of the introduced heterogeneous systems have been explored in the reduction of nitrobenzene derivatives.

“…The magnetic separable nanoparticles have advantages such as insoluble in reaction mixture, paramagnetic nature, and easy separation of nanocatalyst by using magnet which avoids the catalyst filtration; it prevents the aggregation of nanocatalyst which increases the durability of the catalysts, recycling and reusability of catalyst [32]. The researchers paid their efforts to synthesis of magnetic s magnetic separable nanoparticles and their applications in catalysis [33][34][35]. In our recent work, we have developed several facile and greener synthetic routes for nanoparticles and developed their applications in catalysis [36][37][38][39][40].…”

“…Recent reviews on sustainable Suzuki-Miyaura reactions in aqueous media discuss the use of recoverable catalysts, yet these are limited to non-peptidic substrates [11,138,182]. In this respect, several recyclable catalysts [183][184][185][186][187][188][189][190], including silica-or polymer-supported catalysts and magnetically recoverable catalysts, are reported for biaryl formation and could potentially be implemented for transformations of peptide substrates.…”

Abstract:The (site-selective) derivatization of amino acids and peptides represents an attractive field with potential applications in the establishment of structure-activity relationships and labeling of bioactive compounds. In this respect, bioorthogonal cross-coupling reactions provide valuable means for ready access to peptide analogues with diversified structure and function. Due to the complex and chiral nature of peptides, mild reaction conditions are preferred; hence, a suitable cross-coupling reaction is required for the chemical modification of these challenging substrates. The Suzuki reaction, involving organoboron species, is appropriate given the stability and environmentally benign nature of these reactants and their amenability to be applied in (partial) aqueous reaction conditions, an expected requirement upon the derivatization of peptides. Concerning the halogenated reaction partner, residues bearing halogen moieties can either be introduced directly as halogenated amino acids during solid-phase peptide synthesis (SPPS) or genetically encoded into larger proteins. A reversed approach building in boron in the peptidic backbone is also possible. Furthermore, based on this complementarity, cyclic peptides can be prepared by halogenation, and borylation of two amino acid side chains present within the same peptidic substrate. Here, the Suzuki-Miyaura reaction is a tool to induce the desired cyclization. In this review, we discuss diverse amino acid and peptide-based applications explored by means of this extremely versatile cross-coupling reaction. With the advent of peptide-based drugs, versatile bioorthogonal conversions on these substrates have become highly valuable.
