Nano ceria catalyzed synthesis of substituted benzimidazole, benzothiazole, and benzoxazole in aqueous media was written by Shelkar, Radheshyam;Sarode, Sachin;Nagarkar, Jayashree. And the article was included in Tetrahedron Letters in 2013.Electric Literature of C13H8BrNO This article mentions the following:
A series of substituted benzimidazoles, benzothiazoles, and benzoxazoles was synthesized by combining 1,2-phenylenediamine, 2-aminothiophenol, or 2-aminophenol with aryl, heteroaryl, aliphatic, α,β-unsaturated aldehydes in the presence of nano ceria (CeO2) as an efficient heterogeneous catalyst. In the experiment, the researchers used many compounds, for example, 2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9Electric Literature of C13H8BrNO).
2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9) belongs to benzoxazole derivatives. Benzoxazoles belong to the group of well-known antifungal agents with antioxidant, antiallergic, antitumoral and antiparasitic activity. It is found within the chemical structures of pharmaceutical drugs such as flunoxaprofen and tafamidis.Electric Literature of C13H8BrNO
