CuFe₂O₄ magnetic nanoparticles were prepared, characterized and used as a magnetically recoverable nanocatalyst for the one-pot synthesis of phenyl aryl/heteroaryl/benzyl sulfides through the cross-coupling reaction of phenylboronic acid with aryl/heteroaryl/benzyl halides in the presence of S₈ as a sulfur source in PEG400 as a reusable solvent at 80 째C. Also, the synthesis of symmetrical sulfides from aryl/heteroaryl halides using S₈, KF and Cs₂CO₃ in PEG400 at 120 째C is described. The magnetic nanocatalyst was recycled up to 6 times with little loss of activity.
