The 1,3,4-oxathiazolium salts (11,12), which are the first representatives of the six possible classes of aromatic oxathiazolium cations, are readily prepared by N-acylation of the S-acylthiohydroxylamines ( 7,8) followed by cyclization with a strong acid and an acyl anhydride. The positive charge appears to be delocalized to a smaller extent than in analogous dithiazolium salts.
