1-(Hydroxymethyl)-1H-benzotriazole: An Efficient Ligand for Copper-Catalyzed Ullmann-Type Coupling Reaction Leading to Expeditious Synthesis of Diverse Benzoxazoles and Benzothiazoles was written by Singh, Mala;Bose, Priyanka;Singh, Anoop S.;Tiwari, Vinod K.. And the article was included in ChemistrySelect in 2019.Electric Literature of C13H8BrNO This article mentions the following:
Cu-Catalyzed Ullmann coupling of aryl bromides and amides/thioamides was performed for the facile synthesis of diverse benzoxazoles and benzothiazoles I [R = H, 2-Me, 4-Br, etc.; R1 = H, Cl; R2 = H, Br; X = O, S] in the presence of 1-(hydroxymethyl)-1H-benzotriazole as ligand and K2CO3 as base in anhydrous DMF at 120 °C. 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. The benzoxazole moiety is widely found in various natural compounds, which are often found to be biologically active. It is found within the chemical structures of pharmaceutical drugs such as flunoxaprofen and tafamidis.Electric Literature of C13H8BrNO
