mild, general, and efficient copper-catalyzed system for C–S bond formation with high chemoselectivity and wide functional group tolerance is developed. With CuBr as catalyst and 1,2,3,4-tetrahydro-8-hydroxy-quinoline as ligand, the S-arylation of thiols with arylhalides performed well, the activated aryl iodides could take place even at room temperature, and the activated aryl bromides and chlorides

In the presence of copper(I) iodide in hot N,N-dimethylformamide (DMF), a variety of functionalized iodoarenes undergo nucleophilic displacement reaction with sodium arenesulfinates to give the corresponding unsymmetrical diaryl sulfones in moderate to good yields.

arenethlolates in Me2SO at 25°C represents an efficient access to diarylsulfides. A number of evidences suggest the occurrence of a radical, radical-anion SRNlmechanism, the arenethlolate acting both as electron donor and as aryl-radical trapping nucleophile. Valuable improvements with respect to recent SRNl syntheses of diarylsulfides from haloarenes are represented. Inter alia, by the compatibility
