520			_aTranscripción del resúmen publicado por el autor: MoCl5 was found as a new catalyst for the benzylation of anisole. In comparison to the general Lewis acid, such as FeCl3, ZnCl2, and AlCl3, the reactivity of MoCl5 was higher than AlCl3 but lower than FeCl3 under the same reaction conditions. When MoCl5 was supported on HZSM-5 or TS-1 molecular sieve, the yield of this reaction was increased from 45% to 99% or 98%, and the selectivity of para/ortho was promoted from 1:1 to 1.9:1 or 2.2:1, respectively. A mechanism of anisole benzylation over MoCl5 was proposed, which was different from the traditional Friedel-Crafts alkylation mechanism.
