Abstract
Monohalobenzene compounds are iodinated with an iodination reagent selected from the group consisting of (i) iodine monochloride and (ii) I.sub.2 /Cl.sub.2 mixtures having a mol ratio of about 1:3-5:1, in the presence of a catalyst selected from the group consisting of MoCl.sub.5, FeCl.sub.3, lanthanide chlorides and mixtures thereof. Preferably one of chlorobenzene and fluorobenzene is at least partially converted to at least one of para-iodochlorobenzene and para-iodofluorobenzene. Various other aromatic compounds, preferably di- and trichlorobenzene, xylenes, nitrobenzene and ethyl benzoate, are iodinated with an iodination reagent selected from the group consisting of (i) iodine monochloride and (ii) I.sub.2 /Cl.sub.2 mixtures having a mol ratio of about 1:3-5:1, in the presence of a catalyst comprising FeCl.sub.3 and, optionally, a lanthanide chloride.
