Two novel benzothiazole derivatives (2-[(1,3-benzothiazol-2-ylamino)methyl]-1-naphthol (1) and 2-{[(6-methyl-1,3-benzothiazol-2-yl)amino]methyl}-1-naphthol) (2) have been synthesized. The protecting effect of these compounds on low carbon steel (LCS) in 0.1M hydrochloric acid (HCl) solutions as corrosion media was investigated using potentiodynamic polarization technique, and electrochemical…
