During the thermal and catalytic rearrangements of 4-(1,1-dimethyl-2-propenoxy)toluene the Claisen phenol, with inversion of the allyl unit, i.e., 4-methyl-2-(3-methyl-2-butenyl)phenol, is formed primarily.The formation of 2-methyl-2-(3-methyl-2-butenyl)phenol in the catalytic rearrangement with the introduction of o-cresol into the reaction zone shows that this rearrangement has partly intermolecular character.Consequently, the Claisen phenol can also be obtained by an intermolecular path, where this phenol is the most thermodynamically stable isomer.
