A broad range of functionality on p-anisidine substrates as well as sulfinate salts was tolerated under mild reaction conditions to provide the corresponding aryl sulfones in good to excellent yields.1 aHalder, P.1 aHumne, V., T.1 aMhaske, S., B.  uhttps://library.ncl.res.in/content/transition-metal-free-regioselective-one-pot-synthesis-aryl-sulfones-sodium-sulfinates
