Phenylsulfenylation of unsaturated acids and alcohols has been achieved by methyl phenyl sulfoxide (PhSOCH3) and substoichiometric (COCl)2 in CH3CN. The corresponding cyclization products, lactones with a phenylthio group from unsaturated acids were obtained in mediate to good yields, whereas the cyclic ethers with a phenylthio group from unsaturated alcohols in relatively low yields. PhSOH was proposed to be the key active species for phenylsulfenylation, which was generated in situ by the reaction of PhSOCH3 with substiochiometric amount of (COCl)2. Anhydrous HCl could replace (COCl)2 in the reactions to give the comparable results.

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.

A general method for the formation of the cyclic ethers 9, 10, 13, 14, 16 and the lactone 30 is described.The procedure employs benzenesulfenyl chloride prepared in situ in acetonitrile and N,N-diisopropylethylamine to generate a thiiranium (episulfonium) ion intermediate from which the cyclic products arise by internal nucleophilic displacement.In the special case of the norbornene alcohols 1 and 2 the oxethanes 5 and 6 are formed by intramolecular sulfenate ester cycloaddition.

A variety of β-oxygenated selenides, as exemplified by phenylseleno lactones, ethers, and alcohols are converted into olefins by treatment with Me3SiCl and NaI in MeCN; the reaction is stereospecific and can be extended to iodo and thio species.The conversion of 1,3, and 4 into 2-cyclopentene-1-acetic acid, of 5 into 2-(2-cyclopenten-1-yl)ethanol, and of 9 into (Z)-oct-4-ene illustrates the process.
