An asymmetric Mn/TEMPO-Salen complex was utilized as a reducing agent and template for the synthesis of Mn/TEMPO-doped Fe3O4 NPs in situ. The subsequent thermal decomposition of Mn/TEMPO-doped Fe3O4 NPs, as a precursor, provides the highly porous (641 m2 g–1) Mn2O3-doped Fe3O4 NPs. The highly porous NPs was characterized by FTIR, BET, TGA, VSM, ICP, TEM, XRD, UV–Vis, and XPS analyses. High stability and catalytic activity was found for the NPs in the synthesis of α-aminonitriles via the Strecker synthesis from primary and secondary alcohols under mild conditions. TAIm[CN] ionic liquid (IL) was used as an efficient solvent and nitrile-required reagent to synthesis of α-aminonitriles. TAIm[CN] IL could be recycled for several times by a simple recovery and subsequent treatment. Also, the catalytic activity of the NPs was evaluated toward the selective alcohol oxidation to carbonyl …
