Fluoro-substituted carbocyclic compounds are prepared by (A) reacting hydrogen fluoride with a chloro-cyclohexenyl compound of the formula STR1 where R1 and R2 are independently selected from the group consisting of --H, --CH2 OH, --COF, --COCl, --CF3, --CN, STR2 and --CH2 R, where R is --H or alkyl of 1-4 carbon atoms, to form a gem-dihalocyclohexane compound of the formula STR3 where X is chlorine and R1 and R2 are as defined above, (B) dehydrohalogenating the gem-dihalocyclohexane compound in the vapor phase to form a fluoro-cyclohexenyl compound of the formula STR4 (C) contacting the fluoro-cyclohexenyl compound, in the vapor phase, with a dehydrogenation catalyst to form a fluoro-substituted aromatic compound of the formula STR5
