Herein, we present a copper-mediated decarboxylative sulfonylation of arylacetic acids with sodium sulfinates that provides viable access to sulfone compounds. This protocol features readily available feedstocks, simple operations, high regioselectivities, and moderate to good yields. The newly obtained products could be converted to other useful compounds. Importantly, the products and their derivatives exhibited potent antitumor activities in vitro, which were tested by MTT assay.

Relative electrophilic activities of substituted nitroarenes in the vicarious nucleophilic substitution (VNS) reaction with carbanion of chloromethylp-chlorophenyl and bromomethyl phenyl sulfones, 1 and 2, were determined via competitive experiments. The results are in good agreement with relative activities determined earlier in the competitive experiments with carbanion of chloromethyl phenyl sulfone 3 confirming reliability of these data. On the other hand, analogous competitive experiments with tertiary carbanions of chloroform and 1-chloroethyl phenyl sulfone gave results much affected by steric effects thus the VNS reaction with these carbanions cannot be used for evaluation of electrophilic activities of nitroarenes.

3-Carboxypyridinium chlorochromate (CPCC) in the presence of aluminium chloride is a very efficient reagent for the selective oxidation of sulfides to sulfoxide and sulfones in solution and under microwave irradiation. It is noteworthy that different functional groups including carbon-carbon double bonds, ketones, oximes, aldehydes, ethers, and acetals were tolerated under these reaction conditions.

Benzyl and para-substituted benzylcobaloximes react with substituted arenesulphonyl chlorides under photochemical and anaerobic conditions at 0 deg C to give a variety of products including the sulphones, bibenzyls, and benzyl ethers of dimethylglyoxime in variable yields.However, when the reactions are carried out in the presence of a 1 mol excess of pyridine, the yield of sulphones is increased by at least 20percent in each case.The corresponding yield of bibenzyls is decreased and no trace of the benzyl ether of dimethylglyoxime is formed.On the other hand, the reaction of heteroaromatic methyl cobaloximes with arenesulphonyl chlorides form the corresponding sulphones as the exclusive organic product in good yield and with no side products.The reactions are interpreted in terms of a direct attack of the arenesulphonyl radical on the α carbon of the benzyl and heteroaromatic methyl ligand.
