The characteristic properties of methane sulfonic acid catalysts metallic-OTf catalysts heteropoly acid catalystszeolite catalysts and ionic liquid catalysts are summarized. The new catalysts are superior to the traditional ones in several aspects less consumptioneasier operationshorter reaction timehigher catalytic activitybetter catalytic selectivity reusability and less pollution to the environment. Finally the prospects of the research and application of the novel catalysts of Fries rearrangement reaction are presented.
