A simple and efficient procedure for the synthesis of unsymmetrical diaryl selenides has been developed by magnetically separable CuFe2O4 nanoparticle catalyzed reactions of organoboranes with PhSeBr in recyclable PEG-400 medium at 80 °C and Cs2CO3 as base. Using this protocol, a variety of unsymmetrical selenides were obtained in good to excellent yields. The copper ferrite nanoparticles were magnetically separated, recycled, and reused up to four cycles.
