Abstract
1,2,3,6-Tetrahydrobenzocyclobutene-3,6-dione underwent thermal ring opening of the four-membered ring at 140°C to generate 5,6-dimethylene-2-cyclohexene-1,4-dione. This is a highly reactive substance and was trapped as dimers or Diels-Alder adducts giving polycyclic 1,4-benzoquinones. Intramolecular rearrangements preferably took place in some derivatves.
