The Pummerer rearrangement of 1,5-dithiacyclo-octane 1-oxide with acetic anhydride: evidence for formation of the disulphide dication
Abstract
The Pummerer reaction of 1,5-dithiacyclo-octane 1-oxide with acetic anhydride afforded the α-acetylated cyclo-octane via the intermediate formation of the disulphide dication.
