Stereoselective synthesis of (E)-alkenyl sulfones from alkenes or alkynes via copper-catalyzed oxidation of sodium sulfinates

Alkenyl sulfones can be stereoselectively synthesized from alkenes or alkynes using sodium sulfinates. The reaction can be performed by a copper-catalyzed oxidation of sodium sulfinates in air. The reaction of alkenes gives (E)-alkenyl sulfones via anti addition of sulfonyl cation and elimination process. Furthermore, the employment of alkynes produces (E) β- haloalkenyl sulfones in the presence of potassium halides. Georg Thieme Verlag Stuttgart · New York.

Radical Induced Cyclisations of Some Cyclic Unsaturated Allylic Sulphones

The cyclisations of unsaturated allylic p-tolyl sulphones to give ring compounds with adjacent vinyl and p-tolylsulphonylmethyl substituents (Scheme 2) is shown to be a feasible process by the conversion, in satisfactory yield, of the allylic ether (5; R=

Synthesis of Allyl and Dienyl Sulphones via Iodosulphonylation of Conjugated Dienes

The iodosulphonylation of conjugated dienes with sodium or mercury(II) toluene-p-sulphinate and iodine yields δ-iodoalkenyl sulphones stereoselectively.These compounds undergo stereospecific dehydrohalogenation to afford dienyl sulphones and nucleophilic

REACTION OF 1,3-DIENES WITH ARYLSULFONYL THIOCYANATES

At room temperature arylsulfonyl thiocyanates add to conjugated dienes with the formation of 1,4-addition products.In all cases the organic sulfonyl radical is fixed at the least substituted carbon atom of the 1,3-diene system.In reaction with triethylamine or sodium ethoxide the adducts which form eliminate thiocyanic acid with the formation of conjugated dienyl sulfones.
