Article abstract of DOI:10.1016/S0040-4039(00)73665-3

Pyrolysis of trans-3,4-dimethyl-3,4-diphenylcyclobutane-1,2-dione results in an isomerization interpreted to involve formation of a dioxatetramethyleneethane biradical. This biradical would arise from a hitherto unprecedented 3,4 bond cleavage.
