CuFe2O4 magnetic nanoparticle catalyzed odorless synthesis of sulfides using phenylboronic acid and aryl halides in the presence of S8

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 crosscoupling reaction of phenylboronic acid with aryl/ heteroaryl/ benzyl halides in the presence of S-8 as a sulfur source in PEG400 as a reusable solvent at 80 degrees C. Also, the synthesis of symmetrical sulfides from aryl/ heteroaryl halides using S-8, KF and Cs2CO3 in PEG400 at 120 degrees C is described. The magnetic nanocatalyst was recycled up to 6 times with little loss of activity.
