Irradiation of diketone 4 or cyclobutenedicarboxylic anhydride 6 in an argon matrix leads to tetramethylcyclopentadienone (5).On the contrary, the valence isomeric anhydride 7 gives cyclobutadiene 3 via lactone 8 which also can be prepared directly from α-pyrone 10.Tetramethyltetrahedrane (2) cannot be detected.
