Abstract: The reactions of imidazoles with a series of dialkyl and alkylene carbonatesafforded the corresponding N-alkyl- andN-(hydroxyalkyl)imidazoles with highyields. The reactivity of dialkyl carbonates decreases in the series dimethyl> diethyl > dibutyl carbonate. Ethylene carbonate is a more efficientalkylating agent than trimethylene carbonate. The mechanisms of alkylation ofimidazole with dimethyl carbonate and ethylene carbonate were studied by DFTquantum chemical calculations at the B3LYP/6-311++G(d,p) level of theory.
