Infobox references

The suffix "-one" indicates that it is a ketone.[3] The systematic name of the molecule is 3,4,4,5-tetramethylcyclohexa-2,5-dienone.[4][5]

Although it is a dienone and thus has the necessary structure for Dienone-Phenol Rearrangement, the methyl groups in positions 3 and 5 of the ring block the movement of the group at position 4, so even the action of trifluoroacetic acid will not cause transformation to a phenol.[6]
