Synthesis of Pd supported on 3,4-diaminobenzoic acid functionalized Fe₃O₄ nanoparticles as a magnetic catalyst for synthesis of 2-methoxy-2-phenylacetonitrile derivative via a strecker-type reaction under ambient and solvent-free conditions

Abstract

Pd supported on 3,4-diaminobenzoic acid 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 a Strecker-type reaction for one-pot synthesis of 2-methoxy-2-phenylacetonitrile derivatives under ambient and solvent-free conditions. Simple procedure, high yields, short reaction time, and 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.
