| Abstract: | Abstract KF/Al2O3 is an efficient solid heterogeneous base catalyst in the one-pot synthesis of 2-substituted benzimidazoles and 2,2′-disubstituted
bis-benzimidazoles from 1,2-phenylenediamines or 3,3′-diaminobenzidines and acid chlorides, anhydrides, and esters at room
temperature. |
