Abstract

Abstract KF/Al 2 O 3 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.
