In a process for producing an iodo-aromatic compound which comprises iodinating an aromatic compound having an electron-donating substituent bonded to the benzene ring with iodine in the presence of a solvent, the improvement wherein about 1/2 to about 10 moles, per mole of iodine added to the reaction system, of nitrogen dioxide (NO.sub.2) is added in the form of NO.sub.2 to the reaction system, and the reaction is carried out in the presence of nitrogen dioxide.

Process for producing iodo-aromatic compounds

Both cyclohexanone and alkyl-substituted or unsubstituted phenol are simultaneously produced, in a one step reaction, by oxidizing, in the liquid phase, an alkyl-substituted or unsubstituted phenylcyclohexane of the formula (I): ##STR1## wherein R represents either a hydrogen atom or a methyl radical with an oxidizing gas containing molecular oxygen therein in the presence of hydrogen bromide.
