- METHOD OF PRODUCING IODIZING AGENT, AND METHOD OF PRODUCING AROMATIC IODINE COMPOUND
-
A method of the present invention, for producing an iodizing agent, includes the step of electrolyzing iodine molecules in a solution by using an acid as a supporting electrolyte. This realizes (i) a method of producing an iodine cation suitable for use as an iodizing agent that does not require a sophisticated separation operation after iodizing reaction is completed, and (ii) an electrolyte used in the method. Further, a method of the present invention, for producing an aromatic iodine compound, includes the step of causing an iodizing agent, and an aromatic compound whose nucleus has one or more substituent groups and two or more hydrogen atoms, to react with each other under the presence of a certain ether compound. This realizes such a method of producing an aromatic iodine compound that position selectivity in iodizing reaction of an aromatic compound is improved.

- Dehalogenation of o-dihalogen substituted arenes and α,α′-dihalogen substituted o-xylenes with lanthanum metal
-
It was found that lanthanum metal caused the dehalogenation of o-dihalogen substituted arenes and α,α′-dihalogen substituted o-xylenes to generate the corresponding benzynes and o-quinodimethanes. When o-dihalogen substituted arenes were allowed to react with lanthanum metal in the presence of dienes, the Diels-Alder products between benzyne and dienes were formed in moderate to good yields. Similarly, the Diels-Alder adducts of o-quinodimethane with dienophiles were obtained, in the reaction of α,α′-dibromo-o-xylenes with lanthanum metal in the presence of dienophiles.

- STOICHIOMETRIC AND CATALYTIC OXIDATIVE IODINATION OF AROMATIC COMPOUNDS IN THE PRESENCE OF NITROGEN-CONTAINING OXIDIZING AGENTS IN AQUEOUS TRIFLUOROACETIC ACID
-
The conditions for oxidative monoiodination of benzene, halogenobenzenes, toluene, halogenotoluenes, and p-toluic acid in solvents based on trifluoroacetic acid were studied.Yields of the respective iodoarenes close to quantitative were obtained in systems containing 10-20 vol. percent of water in the solvent with equimolar amounts of alkali-metal metal iodides in relation to the substrate in the presence of stoichiometric (under anaerobic conditions) or catalytic (in the presence of oxygen or air) amounts of alkali-metal nitrates.The analogous reactions with nitrites can only be conducted under aerobic conditions.These iodinating systems are compared with systems based on acetic acid containing iodine and mixtures of sulfuric and nitric acids.The conditions for the iodination of toluene and for the transformations of the obtained iodotoluenes in the presence of nitrogen-containing oxidizing agents in trifluoroacetic acid solutions were studied in detail.It was shown that p-iodotoluene undergoes ipso-nitrodeiodination to a significant degree under these conditions.It is supposed that the iodinating agent in the investigated systems is trifluoroacetyl hypoiodite.Data on the assignment of the PMR spectra of the synthesized isomeric nitroiodotoluenes and chloroiodotoluenes by a simple additive method are given.
