摘要

A number of substituted 2-pyridin-2-yl-1H-benzoimidazoles and 2-(1H-imidazol-2-yl) pyridines were screened for promoting CuI-catalyzed hydroxylation of aryl bromides, which led to the discovery of the combination of CuI and 5-bromo-2-(1H-imidazol-2-yl) pyridine as an effective catalytic system for this transformation. Both electron-rich and electronic- deficient aryl bromides could be converted into the corresponding substituted phenols in ...
