Penguinone
Penguinone is an organic compound with the molecular formula . Its name comes from the fact that its 2-dimensional molecular structure resembles a penguin. The suffix "-one" indicates that it is a ketone, that is, an acid with double bond between an oxygen and a carbon atom. The systematic name of the molecule is 3,4,4,5-tetramethylcyclohexa-2,5-dienone. 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.〔 〕 ==See also==
