1,3-Dioxetane (1,3-dioxacyclobutane) is a heterocyclic organic compound with formula C2O2H4, whose backbone is a four-member ring of alternating oxygen and carbon atoms.
Derivatives of 1,3-dioxetane are rarely encountered as intermediates in the literature.
Usually, they are prepared via [2+2] cycloadditions of two carbonyl compounds.
Molecular orbital theory calculations suggest that they should be more stable than the 1,2-isomers, which are more intensively studied.
