Alkoxylation reactions of aryl halides catalyzed by magnetic copper ferrite

摘要

Copper ferrite (CuFe_2O_4), which is easy-made, air-stable, low cost, easy separable, and regenerable, was applied as catalyst in an efficient method for C-O coupling reactions between various kinds of unactivated alkyl alcohols and aryl halides. This method only adopts 2.5% mol CuFe_2O_4 catalyst and selectively proceeds to C-O bond formation even sensitive substituents exist in the system.
