Selective aromatic electrochemical fluorination of methyl phenyl sulfone
Shainyan,Danilevich,Bel'skii,Stash,Grigor'eva,Chuvashev
, p. 1462 - 1464 (2002)
Electrochemical fluorination of methyl phenyl sulfone occurs exclusively at the aromatic ring to give isomeric methyl mono- and difluorophenyl sulfones and methyl 3,3,6,6-tetrafluoro-1,4-cyclohexadienyl sulfone.
Study of regioselective methanesulfonylation of simple aromatics with methanesulfonic anhydride in the presence of zeolite catalysts
Smith, Keith,Ewart, Gordon M.,El-Hiti, Gamal A.,Randles, Kenneth R.

Regioselective methanesulfonylation of simple aromatics using methanesulfonic anhydride can be achieved over zeolite catalysts. For example, methanesulfonylation of toluene over various cation-exchanged zeolite β catalysts affords higher para-selectivity in the synthesis of methyl tolyl sulfone than standard Friedel Crafts methanesulfonylation utilising aluminium chloride.
Total Synergistic effect between triflic acid and bismuth(IIIr antimony(III) chlorides in catalysis of the Methanesulfonylation of Arenes
Peyronneau, Magali,Boisdon, Marie-Therese,Roques, Nicolas,Mazieres, Stephane,Le Roux, Christophe
, p. 4636 - 4640 (2007/10/03)
A total synergistic effect between bismuth(III) or antimony(III) chlorides and triflic acid has been observed in the Friedel-Crafts methanesulfonylation of arenes and has resulted in the development of the first efficient catalytic systems usable for the methanesulfonylation of both activated and deactivated arenes. A proposed mechanism to explain the observed effects is also discussed. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
Alkyl aryl sulfones and method of preparing the same
-
, (2008/06/13)
Alkyl aryl sulfones of the formula R--SO2 --AR--Yn, wherein Ar is an aryl compound, Y is a substituent on the aryl compound and R is alkyl or cycloalkyl, and liquid mixtures of positional isomers of the same are prepared by reacting an aryl compound of the formula Ar--Yn, with an alkyl sulfonic acid of the formula R--SO3 H and a phosphorus reagent, preferably under heat. Particularly good yields and pure products are obtained using phosphorus pentoxide. Alkyl aryl sulfones produced by this method are a liquid mixture preferably containing at least two positional isomers, wherein no isomer is present in an amount of more than about 50% of the isomer mixture.
