The rearrangement activity of benzyl aryl ether catalyzed by polyphosphoric acid (PPA) was systematically investigated. Optimal structural tuning of substitutions of electron withdrawing group (EWG) and electron donating group (EDG) at phenolic moiety or benzyl moiety benefits the rearrangement and the regio-selectivity of the rearrangement obeyed the substitution directing rule at the aromatic ring. This readily available rearrangement method is of practical interest for the benzylation of diverse aromatic phenols.
