Claisen Rearrangements with a Twist. Molecular iodine catalyzes the Claisen rearrangement of allyl arylethers and substantially reduces the required reaction temperature for these processes. The resulting allyl phenols rapidly undergo iodocyclizations to afford dihydrobenzofurans, which are important building blocks for medicinal applications. DFT calculations and mechanistic studies provide further
