Synthesis of alkyl sulfones

Recent Literature

A practical, rapid, and efficient microwave (MW) promoted nucleophilic substitution of alkyl halides or tosylates with alkali azides, thiocyanates or sulfinates in aqueous media tolerates various reactive functional groups.

A one-pot synthesis of aryl sulfones from primary alcohols is described. Alcohols were treated with N-bromosuccinimide and triphenylphosphine, followed by addition of sodium arenesulfinate with a catalytic amount of tetrabutylammonium iodide to afford the aryl sulfones in good to high yields.

A new protocol for the β-sulfonation of α,β-unsaturated carbonyl compounds with sodium p-toluenesulfinate employs FeCl₃ as catalyst and TMSCl as additive.

Related An efficient cobalt-catalyzed reductive coupling reaction of alkyl halides with alkenes bearing electron-withdrawing groups in the presence of water and zinc powder in acetonitrile gave the corresponding Michael-type addition products in high yields. The mechanism is discussed. P. Shukla, Y.-C. Hsu, C.-H. Cheng, J. Org. Chem., 2006, 71, 655-658. A Zn/CuI-mediated coupling of alkyl halides with vinyl sulfones, vinyl sulfonates, and vinyl sulfonamides is described. Formamide is a superior solvent for obtaining high yields. M. M. Zhao, C.
