CuI-catalyzed O-arylation of phenols with electron-rich 4-bromoanisole and electron-deficient 3-bromoanisole was described. Electron-deficient 3-bromoanisole showed high reactivity, and electron-rich 4-bromoanisole had low reactivity. O-Arylation of 4-bromoanisole occurred to afford the product by increasing reaction temperature and time. This reaction was applied to the synthesis of 1-chloro-4-(4-methoxyphenoxy)benzene, which was further synthesized to herbicide Clofop.

Key words: cross-coupling, electron-rich, electron-deficient, CuI-catalyzed, O-arylation
