Abstract

We present green methodologies for one-pot and odourless syntheses of unsymmetric and symmetric diaryl sulfides via C─O bond activation using NiFe 2 O 4 magnetic nanoparticles as a reusable heterogeneous nanocatalyst. The synthesis of unsymmetric sulfides is performed using the cross-coupling reaction of phenolic esters such as acetates, triflates and tosylates with arylboronic acid/S 8 or triphenyltin chloride/S 8 as thiolating agents in the presence of base and NiFe 2 O 4 magnetic nanoparticles as a catalyst in poly(ethylene glycol) as solvent at 60–85°C. Also, the synthesis of symmetric diaryl sulfides from phenolic compounds using S 8 as the sulfur source and NiFe 2 O 4 as catalyst in dimethylformamide at 120°C is described. Using these protocols, the syntheses of various unsymmetric and symmetric sulfides become easier than using the available protocols due to the use of a magnetically reusable bimetallic nanocatalyst and avoiding the use of thiols and aryl halides. © 2019 John Wiley & Sons, Ltd.
