PURPOSE: To produce the corresponding aromatic fluorine compound in high yield and selectivity, by reacting a compound having the 1-fluorocyclohexene skeleton in the coexistence of an aromatic nitro compound in the presence of a dehydrogenation catalyst. n CONSTITUTION: A compound having the 1-fluorocyclohexene skeleton expressed by formula I (R 1 WR 5 are 1W5C alkyl, acyl, alkoxycarbonyl, aryloxycarbonyl or H), e.g. 1-fluorocyclohexene, is reacted in the coexistence of an aromatic nitro compound, e.g. nitrobenzene or nitrotoluene, preferably at 0.2W1 molar ratio based on the reaction raw material in the presence of a dehydrogenation catalyst, particularly preferably at least one selected from compounds containing Pd, Pt or Ru to afford the aimed aromatic fluorine compound expressed by formula II, e.g. fluorobenzene. n COPYRIGHT: (C)1987,JPO&Japio |
