Abstract:
The appropriate 1-arylhydrazinecarbonitriles 1a–c are subjected to the reaction with 2-chloro-4,5-dihydro-1H-imidazole (2), yielding 7-(4,5-dihydro-1H-imidazol-2-yl)-2-aryl-6,7-dihydro-2H-imidazo[2,1-c][1,2,4]triazol-3(5H)-imines 3a–c, which are subsequently converted into the corresponding amides 4a–e, 8a–c, sulfonamides 5a–n, 9, ureas 6a–I, and thioureas 7a–d. The structures of the newly prepared derivatives 3a–c, 4a–e, 5a–n, 6a–i, 7a–d, 8a–c, and 9 are confirmed by IR, NMR spectroscopic data, as well as single-crystal X-ray analyses of 5e and 8c.

Abstract:
A practical synthetic route to an important pharmaceutical intermediate 1-methyl-4-phenyl-1H-imidazol-2-amine, via a three-step sequence involving cyclisation, hydrolysis and methylation, is reported. In the process of optimisation, a novel chemical entity was isolated and confirmed to be 2,6-diphenyl-1H-imidazo[1,2-a]imidazole by MS, 1H NMR and 13C NMR. The scale-up experiment was carried out to provide 1-methyl-4-phenyl-1H-imidazol-2-amine in 27.4% total yield.

Extended Abstract Adsorption of imidazole, 4-methylimidazole and guanine on copper in chloride solutions was investigated by a combination of weight loss tests with electrochemical and Raman techniques to understand their inhibition efficiency and interaction with the metal. Results revealed that imidazole and 4-methyimidazole are inefficient while guanine was an efficient inhibitor (86 %) due to formation of a passive film. Guanine was not efficient towards API 5L X65 steel corrosion in HCl (~22 %) and the low efficiency was due to physisorption. The insights obtained with the combination of

Abstract:
Abstract The use of corrosion inhibitors is a common practice used to mitigate internal pipeline corrosion in the oil and gas industry. An organic corrosion inhibitor is a molecule comprised of a head group (hydrophilic part) and an alkyl tail (hydrophobic part). Despite the significant amount of work associating the effect of the head group with the mode of adsorption of the inhibitor (such as bonding, effect on the tilt angle of the tail, and hysteresis), there is a lack of research relating the effect of the head group with the electrochemical processes governing the corrosion of mild steel
