摘要：

The 2-alkylthio-1,3-dithiolium salts 2a-e have been prepared by reaction of 4,5-bis(trifluoromethyl)-1,3-dithiole-2-thione (1) with strong alkylating agents like alkyl perfluorobutanesulfonates or Meerwein salts. The first X-ray structure determination shows a localized double bond in the ring system combined with a trithiocarbenium ion in 2e.
