The oxidation and reduction potentials for eight imidazole-2-thiols [imidazole-2-thio (1a), 1-methyl- (1b), 4,5-dimethyl- (1c), 1,4,5-trimethyl- (1d), 4,5-diphenyl- (1e), benz- (1f), 5-methylbenz- (1g), and 5-nitrobenzimidazole-2-thiol (1h)] have been determined in ethanenitrile-hydrogen chloride solution Substituent effects on E(ox) are observed and are discussed. The pKa’s for thiols 1a, 1b, and 1c have been determined as a function of pH in buffer solutions at five temperatures and constant ionic strength of 0.10M using UV spectroscopy. The ΔH0 (kJ/mol) and ΔS° (J mol-1 K-1) for imidazole-2-thiol (1a), 1-methylimidazole-2-thiol (1b), and 4,5-dimethylimidazole-2-thiol (1c) are 38.2 and -92.9, 34.1 and -107.5, and 45.2 and -80.3, resp.
This compound(2-Mercapto-5-methylbenzimidazole)Reference of 2-Mercapto-5-methylbenzimidazole was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
