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.

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.

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.
