1,3-Diaza-6-oxabicyclohex-3-enes and their 3-oxides were obtained by the photolysis of 2H-imidazole 1-oxides and 2H-imidazole 1,3-dioxides. 1,3-Diaza-6-oxabicyclohex-3-ene 3-oxides are thermally unstable and are converted to the starting 2H-

Treatment of the 4,5-diphenyl-2H-imidazoles (1a-e) with alkyl iodides gives novel 1H+,2H-imidazolium salts (2) and (3).The metho-salt (2) N-methyl protons are readily exchanged for deuterium, and anions formed by the action of base give, with m
