摘要：

5-(2-Furyl)-1-methyl-1H-and 1-methyl-5-(2-thienyl)-1H-imidazoles were synthesized. The electron-withdrawing effect of the 5- and 2-imidazole substituents on the furan ring was studied by H-1 NMR spectroscopy and quantum-chemical calculations. Some electrophilic substitution reactions were investigated (nitration, bromination, sulfonation, hydroxymethylation, formylation, and acylation). In some cases, depending on the reaction conditions, both the furan and thiophene ring and the imidazole fragment undergo electrophilic attack.
