A novel metal-free approach to directly synthesize α-acyloxy sulfides from readily available alkyl sulfides utilizing the hypervalent (diacyloxyiodo)benzene and TBAB reagent combination is reported. This transformation is characterized by its broad substrate scope in moderate to excellent yields, convenient operating conditions and outstanding functional group tolerance.

The Pummerer reaction of acetic anhydride with both alkyl aryl sulfoxides and dialkyl sulfoxides was efficiently promoted by a mesoporous aluminosilicate Al-MCM-41 to afford the corresponding α-acetoxy sulfides in high yields. The catalyst was easily reco
PLUMMERER REARRANGEMENT OF ETHYL METHYLSULFINYLTHIOACETATE

Ethyl methylsulfinylthioacetate undergoes Pummerer rearrangement with thionyl chloride, trifluoroacetic anhydride or with acetic anhydride-trifluoroacetic anhydride mixture, but not with acetic anhydride alone.These reactivities are compared to those for methyl methylsulfinylacetate and ω-methylsulfinylacetophenone and interpreted in terms of the difference in stability of the intermediate sulfinyl carbonium ions.
