Abstract

A series of new mono- and bis-1,2,3-triazole derivatives of 2-benzimidazolethiol were synthesized by three-component copper(I)-catalyzed 1,3-dipolar cycloaddition. The desired heterocycles were obtained in good yields and fully characterized. The corrosion inhibition efficiency of new heterocyclic compounds was investigated on steel grade API 5L X52 in 1 M HCl using electrochemical impedance spectroscopy. The results revealed that these new organic compounds show promising inhibition properties for the corrosion of steel in acidic media.
