PHOTOCHEMICAL FLUORINATION OF PERFLUOROPOLYETHER FUNCTIONAL DERIVATIVES

Article abstract of DOI:10.1016/S0022-1139(00)82403-3

Oligomeric perfluorinated polyethers bearing various carbonylic end groups are reacted, at low or moderate temperatures, with fluorine under the influence of UV light.Carboxylic acylfluoride, and trifluoromethylketone groups are quantitatively cleaved under these conditions, while fluoroformate groups are mainly transformed into stable fluoroxy derivatives.Some mechanistic aspects of these photoreactions are discussed.
