We report a fast, efficient, and metal-free protocol for the synthesis of unsymmetrical biaryl sulfides and aryl–alkyl sulfides (4-methoxy-2-sulfanyl-phenylcarbamates) under catalytic influence of 2,4-dinitrobenzoic acid. The reaction proceeded in a regioselective anti-Michael addition fashion and all the products were obtained within a very short period of time and in good to excellent yields.
