- Perfluoroethanesulfonyl fluoride: Preparation from sultone
-
A procedure was developed for preparing perfluoroethanesulfonyl fluoride by synthesis of hexafluoropropane-2-β-sultone from sulfuric anhydride and perfluoropropene, followed by hydrolysis of the sultone to α- tetrafluoroethanesulfonyl fluoride and fluorination of the latter with elemental fluorine.

- Die elektrochemische fluorierung von alkansulfonamiden und alkandisulfonamiden
-
Alkane sulphonylamides and disulphonylamides are stable in anhydrous (HF)x and undergo quantitative fission of S-N bonds during electrochemical fluorination. Besides NF3, the corresponding perfluoroalkane sulphonyl fluorides and disulphonyl fluorides are formed.

- SYNTHESIS OF PERFLUOROPROPANE-1,3-DISULFONIC ACID AND PERFLUOROBUTANE-1,4-DISULFONIC ACID
-
Perfluoropropane-1,3-disulfonic acid, HO3S-(CF2)3-SO3H, and perfluorobutane-1,4-disulfonic acid, HO3S-(CF2)4-SO3H, have been prepared electrochemically from the alkanedisulfonyl difluorides.Whereas perfluoroalkanemonosulfonyl fluorides can easily be prepared via electrochemical fluorination the situation with disulfonyl difluorides is somewhat more difficult.NMR data are reported for all compounds.

- DIE ELEKTROFLUORIERUNG VON Α-CHLORETHYLSULFOCHLORID
-
The electrochemical fluorination of CH3CHClSO2Cl was studied at different conditions.Besides methane- and ethane-derivates, SO2F2 and SF6, the products formed are the two sulfonylfluorides C2F5SO2F and CF3CFClSO2F.The yield of CF3CFClSO2F was greater at l
