Magnetically Separable CuFe₂O₄ Nanoparticles in PEG: A Recyclable Catalytic System for the Amination of Aryl Iodides

Abstract

A recyclable catalytic system comprising magnetically separable CuFe₂O₄ nanoparticles in a poly(ethylene glycol) medium has been established as an inexpensive, nontoxic, environmentally benign system for the amination of aryl iodides with aqueous ammonia. A wide variety of aryl iodides underwent amination to afford the corresponding aryl amines in moderate to good yields. The catalytic system was recycled five times with consistent activity.

Key words

amination - aryl iodides - aqueous ammonia - CuFe₂O₄ - aromatic amines
