1,156,912. Araliphatic fluoro compounds. NATIONAL RESEARCH DEVELOPMENT CORP. 18 Aug., 1966 [21 May, 1965], No. 21636/65. Heading C2C. A process for the manufacture of a fluorinated organic compound having an aromatic group directly connected to a fluorinated alkyl group comprises reacting an aromatic compound having an aromatic nucleus with a reactive halogeno-substituent, a fluorinated alkane having a reactive halogeno-substituent and metallic copper in a dipolar aprolic organic solvent at between 90‹ and 200‹ C. and separating out the resulting desired fluorinated organic compound formed. The term "reactive halogeno substituent" includes iodine and bromine in general and chlorine when activated, e.g. when attached to a triazine ring or when ortho to a nitro group in a benzene ring. Dipolar aprolic solvents specified include diacyl dialkylamides, dialkyl sulphoxides, pyri - dines and quinolines, pyridine and quinoline N-oxides and hexamethylphosphoramide. Products of which the preparation is described in examples are 1-phenyl heptafluoropropane, 4 - phenyl hexafluorobutanoate, pentadecafluoroheptyl benzene, o - heptafluoropropyl nitrobenzene, 2,2,2 - trifluoroethylbenzene, 1,2 - di - (3 - pyridyl) hexafluoropropane and 1,3 - disubstituted hexafluoropropanes in which the 1 and 3 substituents are the same and are phenyl, m-tolyl, m-methoxyphenyl, m-nitrophenyl, m-acetoxyphenyl, m-ethoxyphenyl, p- and m-methoxy-phenyl-, 4,6-dimethoxy-s-triazinyl- and 3-(#-phenylhexafluoropropyl)-phenyl.
