A recyclable, inexpensive, non‐toxic and environmentally benign catalytic system comprised of magnetically separable copper ferrite (CuFe 2 O 4 ) nanoparticles has been developed for the synthesis of diaryl, alkyl/aryl sulfones. Arylsulfinic acid salts are coupled with various alkyl/aryl halides/boronic acids to afford the corresponding diaryl, alkyl/aryl sulfones in good to excellent yields under the identical catalytic system. A wide range of functional group tolerance, with facile recovery of the catalyst by application of an external magnetic field, and consistently high catalytic efficiency for five consecutive cycles render the protocol operationally attractive.
