During this laboratory session we will use the Claisen rearrangement to transform phenyl allyl ether (1) into 2- allyl phenol (2). The phenol results from the tautomerization of the initial product of the Claisen rearrangement to restore aromaticity as shown below. You have yet to learn that keto-enol tautomerization usually favors the ketone, but in this case the restoration of aromaticity provides a driving force for the formation of the enol). OH Claisen Rearrangement Tautomerization Re-aromatization H 2 Scheme 2....
