A new method for the activation of ethyl benzenesulfenate in electrophilic addition reactions

Reactions of unsaturated compounds with the PhSOEt-SOHal2 and PhSOEt-Me3SiHal systems (Hal = Cl or Br) were proposed as a new route to haloalkyl phenyl sulfides. With acyclic and mono- and bicyclic alkenes and dienes as examples, the

New Synthetic Route for the Preparation of 4-Phenylthio-4-butanolide Derivatives by the Use of the Pummerer Rearrangement

The Pummerer rearrangement reaction of 2- or 3-substituted 4-(phenylsulfinyl)butyric acids in the presence of an excess amount of acetic anhydride and a catalytic amount of p-toluenesulfonic acid in refluxing toluene for 1 h afforded 2- or 3-substituted 4-phenylthio-4-butanolide (17a-f).Thermolysis in pyridine of 4-phenylsulfinyl 4-butanolides, which were prepared by oxidation of 17a-f, afforded 2- or 3-substituted 2- or 3-buten-4-olides.
