Synthesis and characterization of Pd supported on methane diamine (propyl silane) functionalized Fe3O4 nanoparticles as a magnetic catalyst for synthesis of α-aminonitriles and 2-methoxy-2-phenylacetonitrile derivative via Strecker-type reaction under ambient and solvent-free conditions

Pd supported on methane diamine (propyl silane) functionalized Fe3O4 magnetic nanoparticles as an organic-inorganic hybrid heterogeneous catalyst was fabricated and characterized by FT-IR, XRD, SEM, TEM, TGA, VSM, EDX, and ICP-AES techniques. The catalytic activity of the magnetic catalyst was probed through the Strecker-type reaction for one-pot synthesis of alpha-aminonitriles and 2-methoxy-2-phenylacetonitrile derivatives under ambient and solvent-free conditions. Simple procedure, high yields, short reaction time, and the environmentally benign method are advantages of this protocol. The catalyst was readily separated using an external magnet and reusable without significant loss of its catalytic efficiency.
