Synthesis of benzimidazoles from o-phenylenediamines and DMF derivatives in the presence of PhSiH3 was written by Zhu, Jianhua;Zhang, Zhenbei;Miao, Chengxia;Liu, Wei;Sun, Wei. And the article was included in Tetrahedron in 2017.Application In Synthesis of 7-Methyl-1H-benzo[d]imidazole This article mentions the following:
A simple approach to preparation of benzimidazoles from o-phenylenediamines and DMF derivatives, only employing PhSiH3 as promoter without any other additives, was reported. This route provided moderate to high yields with a broad substrate scope. A plausible mechanism for the reaction is proposed based on the spectroscopic characterization (e.g., HRMS and 1H NMR) of the reaction mixture 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 a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols.
