Lewis acid catalyst free synthesis of benzimidazoles and formamidines in 1,1,1,3,3,3-hexafluoro-2-propanol was written by Khaksar, Samad;Heydari, Akbar;Tajbakhsh, Mahmood;Vahdat, Seyed Mohammad. And the article was included in Journal of Fluorine Chemistry in 2010.Application In Synthesis of 7-Methyl-1H-benzo[d]imidazole This article mentions the following:
A simple, inexpensive, environmentally friendly and efficient route for the synthesis of benzimidazole and formamidine derivatives by the reaction of O-phenylenediamines or amines with orthoesters using hexafluoroisopropanol as a solvent/catalyst is described. In the experiment, the researchers used many compounds, for example, 7-Methyl-1H-benzo[d]imidazole (cas: 4887-83-6Application In Synthesis of 7-Methyl-1H-benzo[d]imidazole).
7-Methyl-1H-benzo[d]imidazole (cas: 4887-83-6) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Application In Synthesis of 7-Methyl-1H-benzo[d]imidazole
