A new copper-catalyzed oxysulfenylation reaction of enolates with sodium sulfinates has been disclosed. A series of sulfenylated heterocycles including four- and seven-membered cyclic ether were obtained in mild to good yields. This reaction is proposed to go through a radical process, and the sulfur radical (RS?) may be a reactive species.

The intramolecular sulphoetherification respectively sulpholactonization of alkenols and alkenoic acids can be initiated by addition of electrochemically generated sulphenyl cations starting from disulphides.The reaction can either be initiated by indirect electrochemical oxidation of diphenyldisulphide using bromide as redox catalyst or preferably by direct anodic oxidation of bis(4-methoxyphenyl)disulphide. 5- and 6-membered thioaryl substituted ethers and lactones thus may be generated starting preferably from mono or disubstituted alkenols and alkenoic acids.The reaction occurs as a trans-addition to the double bond while for endocyclic double bonds the new ring is cis-annelated.
