Mack, Arthur G.; Suschitzky, Hans; Wakefield, Basil J. published the artcile< Polyhaloaromatic compounds. Part 43. Inter- and intramolecular reactions of polychloroaromatic compounds with copper>, Name: 2,3,4,6-Tetrachloropyridine, the main research area is Ullmann reaction polychlorohalopyridine copper; chlorohalopyridine Ullmann intermol reaction; pyridine polychloro halo Ullmann reaction.
The Ullmann reaction of 4-bromotetrachloropyridine with Cu in DMF gave products arising from halogen exchange and reduction reaction in addition to the expected coupled products whereas pentachloropyridines gave tetrachloropyridines only. The Ullmann reaction of 4-(o-halophenoxy)- and 4-(o-halothiophenoxy)tetrahalopyridines gave products arising from cyclization, reduction, and halogen transfer. Some Cu reacts initially with the pyridyl rather than the o-haloaryl group. The results suggest the Ullmann reaction proceeds by a mechanism involving a pyridylcopper intermediate. Nucleophilic substitution products of pentahalopyridines with phenols, thiophenols, and aniline, were obtained.
