摘要
The photointerconversion of 1,4-dimethylimidazole and 1,2-dimethylimidazole and the photorearrangements of 1,4,5-trimethylimidazole to 1,2,5-trimethylimidazole and of 1,3,5-trimethylpyrazole to 1,2,4- and 1,2,5-trimethylimidazole are reported. The pathway proposed for the formal interchange of the 2 and 4 positions is supported by the positionally specific photorearrangement of 1.4-dimethylimidazole-2d. © 1969.
