This application describes a compound represented by Formula (I): (I) wherein: Y is a biologically active organic core group comprising one or more of an aryl group, a heteroaryl aryl group, a nonaromatic hydrocarbyl group, and a nonaromatic heterocyclic group, to which Z is covalently bonded; n is 1, 2, 3, 4 or 5; m is 1 or 2; Z is O, NR, or N; X1 is a covalent bond or —CH2CH2—, X2 is O or NR; and R comprises H or a substituted or unsubstituted group selected from an aryl group, a heteroaryl aryl group, a nonaromatic hydrocarbyl group, and a nonaromatic heterocyclic group. Methods of preparing the compounds, methods of using the compounds, and pharmaceutical compositions comprising the compounds are described as well.

Polystyrene supported Al(OTf)3: A stable, efficient, selective, and reusable catalyst for sulfonylation of arenes with sulfonic acids

Cross-linked polystyrene supported aluminium triflate (Ps-Al(OTf) 3) was found to be an efficient and chemoselective heterogeneous Lewis acid catalyst for the direct conversion of arenes to sulfones using sulfonic acids as sulfonylating agents. The solid acid catalyst is stable (as a bench top catalyst) and can be easily recovered and reused without appreciable change in its efficiency.

Total Synergistic effect between triflic acid and bismuth(IIIr antimony(III) chlorides in catalysis of the Methanesulfonylation of Arenes

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.
