Dimerization reactions of six ?-rich N-heteroaromatic compounds (2-7) and five xantin derivatives (8-12) in the presence of platinated palladium-carbon (Pd-Py/C) catalyst were investigated.N-Methylimidazole (2), benzimidazole (4) and N-methylbenzimidazole (5) condensed dehydrogenatively to afford the corresponding symmetric dimers when heated in the presence of Pd-Pt/C catalyst and pyridine oxide (1).On the other hand, imidazole (3), pyrazole (6) and N-methylpyrazole (7) did not dimerize under the same conditions.The same reactions using caffeine (10), 1,7-dimethylhypoxanthine (9) gave the corresponding dimers.
