A copper-catalyzed decarboxylative disulfonylation of alkynyl carboxylic acids with sulfinic acids in aqueous solution has been developed. The reaction provides a straightforward and practical access to (E)-1,2-disulfonylethenes, which are important building blocks in synthetic organic chemistry, and exhibits a good functional group tolerance and excellent stereoselectivity. A possible mechanism for the transformation is proposed.

The treatment of alkynylsetenonium salt with benzenesulfinic acid in iprOH gives (Z)-β-sulfonylvinylselenonium salts in good yields. The alkenylselenonium salts thus prepared react with nucleophiles such as alkoxides, halides, and acetylides to produce β-functionalized (Z)-vinyl sulfones in high yields. Furthermore, we succeeded in the simple stereoselective one-step synthesis of various chiral (Z)-β-alkoxyvinyl sulfones by the use of chiral alcohols.

The reactions of alkenylselenonium salts with chiral secondary alkoxides afforded chiral (Z)-O-alkyl enol ethers in good yields and, especially in the case of sterically hindered secondary cyclic alcohols, the best results were obtained from reactions of

Alkynylselenonium salts 2 and 5 were synthesized and treated with benzenesulfinic acid or its sodium salt in an alcohol. The reactions with sodium benzenesulfinate gave (Z)-β-alkoxyvinylsulfones 6 as main products, while the reactions with benzenesulfinic acid afforded the β-sulfonylvinylselenonium salts 11 and 12 in good yields.
