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.

Alkylation of α-(phenylthio)-ketones or -esters with iodoacetate anion gives 1,4-dicarbonyl compounds which are reduced stereoselectively to β-phenylthio-γ-butyrolactones.Oxidation to sulphoxides and thermolysis provides a general synthesis of β- and γ-substituted Δαβ-butenolides.Treatment of 5,5-dimethyl-4-oxo-3-(phenylthio)-hexanoic acid with NaBH4 gives a single γ-lactone whose PhS and But groups are shown to be cis by X-ray crystal structure determination.

The β-carbon of α,β-unsaturated ketones, esters, lactones, and nitriles can be oxidatively functionalized in a regiospecific manner in a simple sequence of reactions.Michael addition of thiophenol followed by oxidation with N-chlorosuccinimide gives chloro sulfides that readily lose HCl to give 3-phenylthio enones, acrylates, and other vinyl derivatives.
