The author of 《Synthesis of Imidazolium and Benzimidazolium Triiodides》 were Shagun, L. G.; Dorofeev, I. A.; Zhilitskaya, L. V.; Yarosh, N. O.; Larina, L. I.. And the article was published in Russian Journal of Organic Chemistry in 2019. Name: 1H-Benzo[d]imidazol-2-amine The author mentioned the following in the article:
1,3-(Di)acetonylimidazolium and -benzimidazolium triiodides were synthesized in a one-pot fashion by reactions of imidazole, 3-(1H-imidazol-4-yl)prop-2-enoic acid, benzimidazole, benzimidazol-2-amine, and 2-ethylbenzimidazole with 1-iodopropan-2-one and mol. iodine under solvent-free conditions in the absence of a base and catalyst at room temperature The reaction of 1H-benzimidazole-2-thiol with 1-iodopropan-2-one and iodine afforded 2-(2-oxopropylsulfanyl)imidazolium triiodide. The reaction direction and yield did not change when 2-iodo-1-(thiophen-2-yl)ethanone was used instead of 1-iodopropan-2-one. After reading the article, we found that the author used 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Name: 1H-Benzo[d]imidazol-2-amine)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Name: 1H-Benzo[d]imidazol-2-amine
