N-arylation of amines: C–N coupling of amines with arylboronic acids using Fe3O4 magnetic nanoparticles-supported EDTA–Cu(ii) complex in water

Abstract

Fe₃O₄ magnetic nanoparticles-supported EDTA–copper(II) complex (Fe₃O₄-EDTA–Cu(II)) has been prepared and characterized by TEM, SEM, XRD, VSM, TGA, and FT-IR spectrometers. The catalyst was applied for the C–N coupling of arylboronic acids with amines for the preparation of N-aryl compounds. Recovery tests confirm that the catalyst can be easily recovered and reused up to eight times without significant loss of its catalytic activity.
