    Notes: Preparation of Esters of Nonafluorobutanesulfonic AcidA series of new alkyl (2a-e), silyl (6a-1), germyl (7) and stannyl esters (8a, b) of nonafluorobutanesulfonic acid has been prepared by different methods (A-I) e.g. C4F9SO2OR [R = Me,Et, CH2CF3, CH2CCl3, CF3, GeMe3, SnMe3, SnEt3] and C4F9SO2OSiR3 [R = Me, Et, iPr, Bu, H, F, Cl, Ph, Ph2Me, PhMe2, Cl2Me]. These compounds are useful and extremely powerful alkylating or silylating reagents.

    Notes: Alkylation Reactions of 4,5-Bis(trifluoromethyl)-1,3-dithiole-2-thione  -  A First X-ray Structure Determination of a 2-Alkylthio-1,3-dithiolium SaltThe 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.
