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. It can be viewed as a dimer of formaldehyde (COH₂).

Derivatives of 1,3-dioxetane are rarely encountered as intermediates in the literature. Usually, they are prepared via 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.^[1]
