REACTIONS OF HIGHLY ELECTROPHILIC TERMINAL POLYFLUOROALKENES WITH GLYCOLS

Octafluoroisobutylene, methyl perfluoromethacrylate, and N,N-dimethylperfluoromethacrylamide react vigorously with 1,2- and 1,3-glycols in an acetonitrile solution with a large excess of potassium fluoride to form cyclic ketenals, i.e., 2-polyfluoroalkylidene-1,3-dioxolanes and 2-polyfluoroalkylidene-1,3-dioxanes respectively.The reaction of octafluoroisobutylene with glycerol under these conditions leads exclusively to 2-hexafluoroisopropylidene-4--1,3-dioxolane.It is typical that the reaction of glycols with octafluoroisobutylene and N,N-dimethylperfluoromethacrylamide involve the addition of HF released in the reaction to the polyfluoroalkenes; in this case the potassium fluoride acts as carrier of the fluoride ion.Conversely, the reaction of methyl perfluoromethacrylate with glycols involves the participation of potassium fluoride as an acceptor of hydrogen fluoride.
