Abstract
Using chloroacetic acid, p-hydroxyl aromatic aldehydes 1 and aromatic diamines 3 as starting materials, novel bisbenzimidazoles 5 with unsymmetric structure were synthesized via aryloxyacetic acid intermediates 2. Four new intermediates 4 and ten target molecules 5 were characterized by FTIR, 1H NMR, 13C NMR, MS and elemental analysis. Different synthetic methods, including one-pot synthesis and intermittent microwave promotion, were investigated. The research provides a new method and idea for the synthesis of bisbenzimidazoles.
