Regioselective Alkylation of 4(5)-Nitro-1H-Imidazoles in Acidic Media: Study of Temperature Effects

Alkylation of 4(5)-nitro-1H-imidazoles in acidic media with reactive alkylating agents such as benzyl chloride and allyl bromide resulted in the predominant formation of the 5-nitro isomers at lower temperatures (75 deg C) and the 4-nitro isomers at higher temperatures (140 deg C).With less reactive alkylating agents, only the 5-nitro isomers were produced irrespective of temperature.The mechanism was shown to involve quaternization of the initially formed 1-alkyl-5-nitro-1H-imidazoles followed by preferential dealkylation to yield the thermodynamically more stable 4-nitro-1H-imidazoles.
