Abstract

New simplistic, one pot synthesis of series of substituted β-keto sulfones from styrenes, NBS and aromatic sodium sulfinate salts were synthesized by sonication. The reactions were transition-metal catalyst free and the reactions were also co-oxidant free as NBS plays a dual role of both the bromine source and oxidant in green solvent water at moderate temperature.
