Magnetically separable CuFe2O4 nanoparticles in a poly(ethylene glycol) medium are an inexpensive, nontoxic, environmentally benign, and recyclable system for the amination of various aryl iodides with aqueous ammonia to afford the corresponding aryl amines in good yields. The catalytic system was recycled five times with consistent activity.
