Irradiation of both 5,6-dimethylene-2,3-diazabicyclooct-2-ene (1) and 2,3-dimethylenebicyclooctan-7-one (2) matrix isolated in argon yields the 2,3-dimethylene-1,4-cyclohexadiyl diradical (8), which was characterized by its UV and IR spectra.From the decomposition rate of 1, the dimerisation rate of 8, determined by flash photolysis of 1, and the product ratio of the monomeric and dimeric products obtained from 8, the energy well of 8 has been determined to be 23.8 kcal mol-1.
