The rearrangement is regioselective with aryl-substituted epoxides, and products arise from cleavage of the benzylic C O bond. The highly catalytic nature of this method coupled with the fact that the reagent is relatively non-toxic, easy to handle and inexpensive make it an attractive alternative to more corrosive and toxic Lewis acids, such as BF3·Et2O, currently used to effect epoxide rearrangements. © 2001 Elsevier Science Ltd.
