ABSTRACT:
A continuous process for preparing in a Simons electrochemical cell charged with anhydrous liquid HF and a S- and H-containing organic precursor fluorochemical compounds having the formula F.sub.5 S--R.sub.f --X where X is COF or SO.sub.2 F; R.sub.f is a saturated fluoroaliphatic radical having at least 3 fully-fluorinated C atoms; and the F.sub.5 S group is bonded via a S--C bond to 1 of the 3 fully-fluorinated C atoms of the R.sub.f radical.
