By using simple and readily available DMSO as a convenient and environmentally friendly source of sulfur, a practical approach for the Pd-catalyzed decarboxylativemethylthiolation of 2-nitrobenzoic acids was developed. A range of substituents on the aryl group of the ortho-nitrobenzoic acid were compatible with this process.
A novel copper-catalyzed decarboxylative methylthiolation of arenecarboxylate salts has been realized using DMSO as the methylthiolation source. Various potassium arylcarboxylates underwent decarboxylative methylthiolation under air to furnish the corresponding aryl methyl thioethers in moderate to excellent yields. The reaction tolerated a wide variety of functional groups. Notably, the synthesis
