Reactions of 4-bromo-(1a) and 4-chloro-2,4,6-tri-t-butyl-2,5-cyclohexadien-1-one (1b) with imidazole (6b), 1-methyl-(6a), 2-methyl-(6c), 4-methylimidazole (6d), benzimidazole (6e), and 2-methylbenzimidazole (6f) were carried out under various conditions. It was found in these reactions that many products such as the 1-(4-oxo-2,5-cyclohexadienyl)-, 1-(2-hydroxyphenyl)- and 1-(4-hydroryphenyl)imidazoles were formed and that the type of the products depended upon the structures of imidazoles 6.
