CuI-Catalyzed Hydroxylation of Aryl Bromides under the Assistance of 5-Bromo-2-(1H-imidazol-2-yl)pyridine and Related Ligands. -After screening different types of imidazole derivatives, BIP is found to be an effective ligand for the title reaction. Generally, similar yields are obtained with the less expensive KOH compared to CsOH. In the case of substrates (VII) and (VIII), the functional groups do not survive the conditions and acid (VIc) is isolated instead. -(JIA, J.; JIANG, C.; ZHANG*, X.; JIANG, Y.; MA, D.; Tetrahedron Lett. 52 (2011) 43, 5593-5595, http://dx.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
