In three odorless methods for the thioarylation and thioalkylation of different nitroarenes using alkyl halides (Br, Cl), triphenyltin chloride, and arylboronic acids as the coupling partners, Na2S2O3·5H2O, S8/KF, and S8/NaOH systems are found to be effective sources of sulfur in the presence of copper salts. The methods offer use of green solvents, inexpensive catalysts, and user-friendly starting materials.
