Zhang, Yong; Ji, Min published an article in 2019, the title of the article was Iodine Promoted One-Pot Synthesis of 2-Aryl Benzoxazoles from Amidoximes via Oxidative Cyclization and Ring Contraction.Safety of 7-Bromo-2-phenylbenzo[d]oxazole And the article contains the following content:

A mol. I2-promoted one-pot synthesis of 2-aryl benzoxazoles was developed by using amidoximes rather than the limited 2-aminophenols or 2-haloamides as substrates. The amidoxime substrates provided unique and efficient strategies for converting readily available aniline and benzaldehyde precursors into valuable chems. This transformation proceeded smoothly under transition-metal-free conditions through a sequential oxidative cyclization and ring contraction and provided a potential route for introducing certain groups at any site of the scaffold. The experimental process involved the reaction of 7-Bromo-2-phenylbenzo[d]oxazole(cas: 1268137-13-8).Safety of 7-Bromo-2-phenylbenzo[d]oxazole
