Upon heating, dichlorodimethylenecyclobutanes (1, 2, 18) undergo rearrangements that yield benzene derivatives including styrene adducts. Preparation of postulated intermediates (10, 23) and study of their pyrolytic behaviour allow to unambiguously establish the mechanism of formation of the styrene derivatives.
