: Oxiranes are regioselectively cleaved by benzenethiol in presence of cobalt(II) chloride or Co2(CO)8 to the corresponding β-hydroxy sulfides in good yields. A mechanistic study of this reaction reveals that an electron transfer process is involved in these transformations and the reaction is proceeding via the formation of a carbon-cobalt bond.

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.
Scope and limitations of allyl sulphide synthesis by [1,2] and [1,3] phenylthio migration
Brownbridge, Peter,Warren, Stuart
, p. 2272 - 2285 (2007/10/05)
β-Phenylthio-alcohols rearrange in acidic solution (toluene-p-sulphonic acid in benzene under reflux) to give allyl sulphides by phenylthio migration. High yields of single products useful in organic synthesis are obtained with a tertiary or secondary mig
