A highly efficient, base-free, mild protocol for the palladium-catalyzed, copper-activated desulfitative couplings of vinyl and aryl β-nitrothioethers generates a wide variety of conjugated nitroorganics. Orthogonality to traditional SuzukiâMiyaura coupling is demonstrated, as well as synthetic utility, through reductive Cadogan cyclization, for the formation of indoles, carbazoles, and pyrroles.
