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
通过适当取代的三氟甲基乙烯酮的氢化硅烷化反应制备的含氟β,β-二取代三甲基甲硅烷基乙烯基醚与N-(1,1,2,2-四氟-乙基)二甲胺反应生成β,β,β',β'-四取代的二乙烯基醚。开发了将全氟-2-甲基戊-2-烯酸叔丁酯选择性氢氟化成相应饱和酯的条件。后者用 P2O5 热解得到全氟甲基-(丙基)乙烯酮。
