Abstract
The action of o-phenylenediamine on malonic, phenylacetic, acetic acid and on acetic anhydride was studied. Four products were insulated respectively: 2,2’-bidibenzimidazolylmethane chloride (a), 2-benzylbenzimidazolium chloride (b), 2 méthylbenzimidazolium chloride (c) and o-phenylenediacetamide (d). Their structures are supported by 1HNMR, I.R., and mass spectrometry. Their inhibiting effectiveness was given in decreasing order: a > d > b > c according to electrochemical measurements.
