The corrosion inhibitive efficiency of diverse 1,2,3-triazolyl benzyl glucoside-, galactoside- and mannoside-serine/threonine conjugates readily synthesized via Cu-I-catalyzed azide-alkyne cycloaddition reaction (Cue-AAC) for mild steel in HCl was examined via electrochemical impedance spectroscopy. The results indicate that these compounds are potent corrosion inhibitors even in highly concentrated HCl solutions. The potential mechanism of three inhibitors was characterized in detail via polarization and isotherm calculations. This study implies that benzyl glycoside-amino acid hybrids effectively constructed via the Cue-AAC between the highly biocompatible sugars and amino acids may represent a new class of promising and potentially green corrosion inhibitors.
