“…Rosin, a resin obtainable from pine trees, had its structure modified via two synthetic procedures involving heating and dehydration, furnishing RI (Figure 12) [78]. Weight loss A eugenol oligomer (EO) was prepared in a single step, using BF 3 •OEt 2 as an initiator, with a high yield (72.3%) as a green corrosion inhibitor (Figure 13) [82]. One of its main features was thermal stability since the first structural cracking only occurred above 629 K due to polymeric chain rupture.…”

Organic molecules are gaining special attention over the last years in the corrosion area thanks to their general low achievable cytotoxicity, structural versatility, and environmentally friendly obtainment methods. Under those approaches, synthetic organic motifs have attracted the interest of researchers due to their variated methods of obtention through molecular manipulation via diverse chemical reactions, allowing the production of adequately planned structures or repurposing their original application in the case of drugs. This review summarizes general aspects that are desired in organic molecules as corrosion inhibitors, presenting selected works published in the 2022–2023 period and emphasizing the importance of finding novel and different organic corrosion inhibitors. Patents were not considered in this review. Scifinder, Google Scholar, and Web of Science were employed as databases. Mathematical and analytical methods involved in the search for corrosion inhibitors are out of this review’s scope.
