An Overview on the Performance of 1,2,3-Triazole Derivatives as Corrosion Inhibitors for Metal Surfaces

Abstract

This review accounts for the most recent and significant research results from the literature on the design and synthesis of 1,2,3-triazole compounds and their usefulness as molecular well-defined corrosion inhibitors for steels, copper, iron, aluminum, and their alloys in several aggressive media. Of particular interest are the 1,4-disubstituted 1,2,3-triazole derivatives prepared in a regioselective manner under copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reactions. They are easily and straightforwardly prepared compounds, non-toxic, environmentally friendly, and stable products to the hydrolysis under acidic conditions. Moreover, they have shown a good efficiency as corrosion inhibitors for metals and their alloys in different acidic media. The inhibition efficiencies (IEs) are evaluated from electrochemical impedance spectroscopy (EIS) parameters with different concentrations and environmental conditions. Mechanistic aspects of the 1,2,3-triazoles mediated corrosion inhibition in metals and metal alloy materials are also overviewed.

Click chemistry: A fascinating, Nobel-winning method for the improvement of biological activity

“…In fact, the 1,3-dipolar cyclization of Huisgen which occurs with the absence of a catalyst, cannot be basically classified in click chemistry since it is a nonselective reaction that progresses slowly and has a mechanism in which 1,4-and 1,5-disubstituted products are formed in equal proportions (Figure 1). When the heat-assisted reaction occurred, the probability of attack of the azide group that triggers the reaction to both sides of the alkyne group increases, resulting in the formation of these 1,4-and 1,5-products (in a ratio 1:1) and reducing the yield [34,35] .…”

“…2 Furthermore, 1,2,3-triazole derivatives are extensively used industrially as dyes, corrosion inhibitors, sensors, and light stabilizers. 3 In synthetic chemistry, 1,2,3-triazole derivatives are used as intermediates for the generation of α-iminocarbenes and are frequently used in various molecular transformation reactions. 4 In chemical biology, biomolecules have been chemically modified using 1,2,3-triazole derivatives; the click reaction between alkynes and azides is used for the modification and occurs even in water and under biocompatible conditions in the commonly named bioconjugate chemistry field.…”

Intriguing interactions of triazolyl organosilane with copper (II) ion, blue copper protein, and silica nanoparticles: Spectral and theoretical approach

“…[31,32] 1,2,3-triazole scaffold has substantiated to be a competent binding skeleton, and their prevalence in chemosensors can be accredited to their ability to bind cations by providing nitrogen donor sites. [33,34] Moreover, organosilanes have multifaceted applicability in optical sensing, drug delivery, and polymer chemistry and are promising materials to increase the adhesion of organic matrices to inorganic substrates. [35,36] In this current study, 2-Amino-4-chlorophenol is the cardinal motif and has attracted the curiosity of chemists owing to its use as a raw material in dye manufacture and also as an intermediate in chemical industries.…”
