accompanied by the reduction of two of four double C=N bonds in macrocyclicSchiff"s bases formed was studied by DFT (gradient-corrected PBE functional, TZ2p basis set). In the first step, [1+1] Schiff"s base is formed and disproportionates further to afford amine and benzoimidazolylphenols. Two new macrocyclic polydentate ligands containingtwo CH2—NH moieties in the rings were synthesized. The reduction
