3,5,9,12-Tetra-tert-but­yl-10,14-dicyclo­hex­yl-2,8-dioxatetra­cyclo­[5.4.0.2^1,9.1^3,7]tetra­deca-4,12-diene-6,11-dione

The title compound, C₄₀H₆₂O₄, is formed by γ irradiation and contains a tetra­cyclo­[5.4.0.2^1,9.1^3,7]tetra­decane moiety. The cage consists of bicyclo­[2.2.2]octa­ne and bicyclo­[3.2.1]octa­ne rings, which are connected via a C—C single bond that is common to both rings. The title compound is formally a dimer of the adduct of a cyclo­hex­yl radical and a 3,5-di-tert-but­yl-ortho-quinone.
