“…The designed magnetic catalysts found high ragio-and chemo-selectivity for the reduction of nitro compounds under the environmentally-friendly solvent, glycerol, as a hydrogen source, along with a high level of reusability [43]. In another effort, Gawande and colleagues introduced a sustainable protocol for the reduction of aromatic nitro compounds using a magnetically-separable and reusable magnetite supporting gold nanocatalysts under mild reaction conditions [44].…”

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 nitro and nitrile groups in aromatic and aliphatic compounds containing various reducible substituents such as carboxylic acid, ketone, aldehyde and halogen are selectively reduced to the corresponding amines in water as a green solvent with excellent yields by employing NaBH 4 in the presence of Fe 3 O 4 @PAMAM/Ni(0)-b-PEG nanocatalyst. The morphology and structural features of the catalyst were characterized using various microscopic and spectroscopic techniques. The designed catalyst system because of it being covered with hydrophilic polymers is soluble in a wide range of solvents (e.g. water and ethanol) and suitable for immobilizing and stabilizing Ni nanoparticles in aqueous mediums. In addition, the catalyst can be easily recovered from a reaction mixture by applying an external magnetic field and can be reused up to six runs without significant loss of activity.

“…The catalyst was reused eight times without any significant loss in catalytic activity and selectivity. 11 (C) Shi and co-workers used glycerol as the hydrogen source in a Au/Ag-Mo-nanorods catalyzed tandem reaction of alcohols and nitrobenzenes, which generated N-alkyl amines and imines. The reaction involved reduction of nitrobenzene, amine-aldehyde coupling, and imine reduction.…”
