Abstract (en)
[origin: US4908107A] The invention relates to a process for preparing compounds of the formula (I) R1-O-CF=CF2 by elimination of halogen atoms from compounds of the formula <IMAGE> (II) by electrolysis. The compounds of the formula (II) are electrolyzed in an undivided or divided electrolysis cell in an organic liquid which can also contain water at a temperature from -20 DEG C. to the boiling temperature of the electrolyte or catholyte at a current density of 1-500 mA/cm2 at a cathode made of lead, cadmium, zinc, copper, tin, zirconium, mercury, alloys of these metals or carbon.
