- TRIFLUOROMETHYLATION OF AROMATIC COMPOUNDS WITH BIS(TRIFLUOROACETYL) PEROXIDE
-
Bis(trifluoroacetyl) peroxide was found to be thermally stable, and trifluoromethylation of aromatic compounds was studied using this peroxide.Trifluoromethylation of electron-rich benzenes, furan, thiophene, or their benzo derivatives proceeded with the peroxide in moderate to high yields.

- PERFLUOROALKYLBENZENESULFONYL CHLORIDES, PERFLUOROAKYLNAPHTHALENESULFONYL CHLORIDES, AND THEIR METAL SALTS
-
Meta-perfluoro-n-alkylbenzenesulfonyl chlorides and 1-perfluoro-n-alkylnaphthalene-5-sulfonyl chlorides were synthesized from the corresponding perfluoroalkylaromatics in good yield by the action of chlorosulfonic acid.From the acid chlorides, salts (RSO3M, where M = Li, K, Ba, Zn and Al) were prepared and their TGA curves obtained.With the exception of the aluminum salts, the materials were stable to at least 350 deg C.All salts were essentially insoluble in Cl(CFClCF2)3-4Cl.

- Method for production of fluorine-containing aromatic derivative
-
A fluorine-containing aromatic derivative is produced by causing a di(haloacyl)peroxide to react upon benzene, a mono-substituted benzene, naphthalene, or a mono-substituted naphthalene thereby introducing an X(CF2)n -group into the benzene ring or the naphthalene ring.
