标题:Synthesis of perfluoroaryl-substituted compounds
发明人：FRAZIER KEVIN A
权利人:DOW CHEMICAL CO
摘要:Perfluoroaryl-substituted compounds are prepared from perfluoroaryl compounds, particularly tris pentafluorophenyl borane is prepared from hexafluorobenzene. The method comprises contacting a perfluoroaryl compound with an organomagnesium reagent in the presence of a catalyst to form a perfluoroaryl magnesium compound, and contacting the perfluoroaryl magnesium compound with a trihalide element to form a tris perfluoroaryl-substituted compound.

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.

标题:Method of producing Ph3 C[B(C6 F5)4 ]
发明人：DOELLEIN GUENTHER
权利人:SOLVAY DEUTSCHLAND
摘要:A method for producing Ph3C[B(C6F5)4] in an improved yield by reacting LiB(C6F5)4, which has not been isolated between production and use, with Ph3CCl preferably in a molar ratio of LiB(C6F5)4 to Ph3CCl of 1:(1+/-0.05), and preferably in the presence of a hydrocarbon solvent such as an aliphatic hydrocarbon containing from 5 to 8 carbon atoms, to give a Ph3C[B(C6F5)4] product; optionally evaporating the hydrocarbon solvent; extracting the resulting Ph3C[B(C6F5)4] product; separating insoluble LiCl, and isolating the product. The product may be isolated, for example, by freeing it of solvent, thereafter dissolving the product in toluene to form a toluene solution, introducing the toluene solution into a hydrocarbon solvent to form crystals of the product, and recovering the crystals. In the method, the LiB(C6F5)4 is used in the form of a hydrocarbon preparation, preferably a reaction mixture obtained in the synthesis of LiB(C6F5) 4, the concentration of may be adjusted by concentrating or diluting as needed to obtain a preferred LiB(C6F5)4 concentration of from 20 to 300 grams/liter.
