Dioxetane
A dioxetane or dioxacyclobutane is an organic compound with formula C2O2H4, whose backbone is a four-membered ring of two oxygen atoms and two carbon atoms. There are two isomers: * 1,2-dioxetane where the oxygen atoms are adjacent. * 1,3-dioxetane where the oxygen and carbon atoms alternate. {{Chemistry index ...

1,3-dioxetane
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 Formaldehyde ( , ) (systematic name methanal) is a naturally occurring organic compound with the formula and structure . The pure compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde (refer to section F ... (COH2). Derivatives of 1,3-dioxetane are rarely encountered as intermediates in the literature. Usually, they are prepared via +2cycloadditions 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.
