1-Methylbenzimidazole (cas: 1632-83-3) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Name: 1-Methylbenzimidazole

Visible-light-induced aerobic oxidative desulfurization of 2-mercaptobenzimidazoles via a sulfinyl radical was written by Fu, Mei;Ji, Xiaochen;Li, Yongtong;Deng, Guo-Jun;Huang, Huawen. And the article was included in Green Chemistry in 2020.Name: 1-Methylbenzimidazole This article mentions the following:

A mild transition-metal-free non-toxic aerobic photoredox system was found to enable highly efficient desulfurization of 2-mercaptobenzimidazoles I [R = H, Me; R1 = H, Ph, but-3-en-1-yl, (2-(trimethylsilyl)ethoxy)methyl, etc.; R2 = H, OMe, Cl, t-Bu, etc.; R3 = H, F, Cl, Br, Me; R2R3 = -CH=CH-CH=CH-; X = SH] and 6-methoxy-3H-imidazo[4,5-b]pyridine-2-thiol, 1H-Imidazo[4,5-b]phenazine-2-thiol. This viable catalytic system includes Rose Bengal in a low catalyst loading as a photosensitizer and cheap, non-toxic NaCl in a catalytic amount as an additive, combined with an oxygen atm. This protocol provides an important alternative access to a broad range of benzimidazoles I (X = H) and 6-methoxy-3H-imidazo[4,5-b]pyridine, 1H-imidazo[4,5-b]phenazine/deuterated benzimidazoles e.g., I (X = D) and 6-methoxy-3H-imidazo[4,5-b]pyridine-2-d product in generally high yields with good tolerance of various synthetically and pharmaceutically useful functionalities. The mechanistic studies reveal that both single electron transfer and energy transfer probably occur in the initial step and a sulfinyl radical intermediate is involved in the key desulfurization process. In the experiment, the researchers used many compounds, for example, 1-Methylbenzimidazole (cas: 1632-83-3Name: 1-Methylbenzimidazole).
