Sulfonic acid functionalized imidazolium salts/ FeCl3 as novel and highly efficient catalytic systems for the synthesis of benzimidazoles at room temperature
Scientia Iranica Vol. 18, No. 6, 1365–1371
چکیده
Ionic liquid 3-methyl-1-sulfonic acid imidazolium chloride/ FeCl 3 , as well as ionic liquid 1, 3-disulfonic acid imidazolium chloride/ FeCl 3 catalytic systems, efficiently catalyzes the condensation of benzene-1, 2-diamine with aromatic aldehydes in the presence of atmospheric air as a green oxidant in ethyl acetate at room temperature to afford benzimidazole derivatives in high yields and in short reaction times. The reaction is also efficiently performed when carboxylic acids are used instead of aldehydes.
