“…[3] In general, compounds containing N, O, S and P heteroatoms and/or π-electron conjugated functions are considered to be a great candidate for the anti-corrosive inhibitors, since such these functions make for the adsorption of inhibitors themselves on the metal surface mainly recurring to physical and/or chemical interactions. [4,5] In this regard, azole-type derivatives, such as imidazole, [6,7] pyrrole, [8] triazole, [9] pyrazole, [10] pyridine, [11] pyrimidine, [12] pyrazine, [13] and some Schiff and Mannich bases, [14,15] may perfectly fulfil the requirement for the chemical structure of inhibitors. Unfortunately, since many organic inhibitors are unhealthy and environ-mentally unfriendly, their use would result in a serious threat to human health and life, and the living environment, which motivates us to search for more suitable alternatives to overcome this challenge facing chemists.…”
