- Selective hydrolysis of pentafluorobenzotrichloride
-
Selective hydrolysis of pentafluorobenzotrichloride has been studied in the presence of a catalytic amount of iron(III) chloride. The main products are pentafluorobenzoyl chloride, pentafluorobenzoyl fluoride, and 4-chlorotetrafluorobenzoyl chloride. The two latter products are formed by hydrolysis of dichlorofluoromethylpentafluorobenzene and 4- chlorotetrafluorobenzotrichloride which result from halogen exchange between the methyl group and aromatic ring in the initial pentafluorobenzotrichloride. A probable mechanism for halogen exchange is proposed.

- PREPARATION OF POLYFLUOROBENZOTRIHALIDES BY THE REACTIONS OF OCTAFLUOROTOLUENE AND ITS DERIVATIVES WITH ALUMINUM HALIDES. SYNTHESIS OF POLYFLUOROSTILBENES AND DECAFLUOROTOLAN
-
Reactions of some polyfluoro aromatic compounds containing a CF3 group with aluminum halides (AlCl3, AlBr3) were studied.In these reactions there occurs the replacement of fluorine atoms by chlorine or bromine both in the side chain in aromatic ring.Treat

- FORMATION OF POLYFLUOROTRICHLOROMETHYLBENZENES FROM PENTAFLUOROBENZENE AND CCl4 IN THE PRESENCE OF AlCl3
-
The reaction of pentafluorobenzene with CCl4 in the presence of AlCl3 gives p-chloro-o,o,m,m-tetrafluorotrichloromethylbenzene as the major product along with pentafluorotrichloromethylbenzene and bis(p-chlorotetrafluorophenyl)dichloromethane.

- REACTIONS OF PENTAFLUOROPHENYLHYDRAZINE AND SOME OF ITS N'-ACYL DERIVATIVES WITH COMPOUNDS CONTAINING A TRICHLOROMETHYL GROUP IN THE PRESENCE OF ALUMUNIUM CHLORIDE
-
The reactions of pentafluorophenylhydrazine and also of N'-benzoyl-, N'-pentafluorobenzoyl-, and N'-acetylpentafluorophenylhydrazines and decafluorohydrazobenzene with CCl3R (R=Cl, C6H5, C6F5) in the presence of aluminium chloride were investigated.The main products from the reaction of pentafluorophenylhydrazine with the reagents were N-pentafluorophenylhydrazonodichloromethane and N-pentafluorophenylhydrazonoaryl chlorides.Derivatives of 1,3,4-oxadiazol-2-in-5-one were formed in the reactions of N'-acylpentafluorophenylhydrazines with carbon tetrachloride in the pres ence of aluminium chloride.When heated with carbon tetrachloride and aluminium chloride, decafluorohydrazobenzene disproportionates with the formation of decafluoroazobenzene and pentafluoroaniline.
