Abstract

Abstract Fluorine-containing β, β-disubstituted trimethylsilyl vinyl ethers prepared by hydrosilyla-tion of appropriate substituted trifluoromethylketenes react with N-(1, 1, 2, 2- tetrafluoro-ethyl) dimethylamine to give β, β, β', β'-tetrasubstituted divinyl ethers. Conditions for selective hydrofluorination of tert-butyl perfluoro-2-methylpent-2-enoate into the corresponding saturated ester were developed. Pyrolysis of the latter with P 2 O 5 afforded ...
