专利号:US-3880943-A 优先权日:1963-08-12 标 题:Highly fluorinated organic compounds and synthesis of perfluorostyrene 发明人:WALL LEO A; ANTONUCCI JOSEPH M 权利人:US NAVY 摘要:New fluorinated substituted ethylenic compounds which are 2,3,4,5,6-pentafluoro- Alpha -(trifluoromethyl) benzyl alcohol, (1,2,2,2-tetrafluoroethyl)perfluorobenzene and (1-bromo-1,2,2,2tetrafluoroethyl)perfluorobenzene. The new compounds are useful as intermediates in the preparation of perfluorostyrene. Pyrolysis of the aforesaid perfluorobenzenes gives perfluorostyrene and of the first of these perfluorobenzenes, Alpha -hydroheptafluorostyrene, also.
