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.

, p. 36112 - 36116 (2017/07/27)
A solvent-dependent sulfonylation of arylethynylene bromides with sodium arylsulfinates has been developed. The (E)-1,2-bis(arylsulfonyl)ethylenes were formed in DMSO, while the arylacetylenic sulfones were obtained in toluene. Utilizing simple and readily available starting materials, the sulfonylation products were generated with good selectivities and yields without the need for a metal catalyst or oxidant.

The invention provides a synthesis method of a disulfonyl olefin derivative. The method is characterized in that raw materials comprising alkynyl bromide and sulfinate undergo a reaction in an organic solvent by adopting a strong acid as a catalyst in order to obtain the disulfonyl olefin derivative; and the organic solvent is any one or more of dimethyl sulfoxide, acetonitrile, N,N-dimethyl formamide or 1,4-dioxane. The reaction is a serial reaction process , so the method avoids a metal catalyst and a strong oxidant; the method also has the advantages of simple and easily available reaction materials, the safe and simple reaction operation, environmentally-friendly reaction process, good substrate applicability, good function group tolerance and realization of high separation yield under optimized conditions; and the disulfonyl olefin derivative synthesized in the invention is an important sulfone compound, and is also a highly useful synthon.
