On catalytic hydrogenation over Pd-C under normal conditions cubane (10) takes up 3 mol of hydrogen in a few hours.Bicyclo<2.2.2>octane (13) is formed as the main product, and tetracyclo<4.2.0.02.5.03.8>octane (11, secocubane) and tricyclo<4.2.0.02.5>octane (12, nortwistbrendane) have been identified as intermediates.The hydrogenolysis of dimethyl 1,4-cubane dicarboxylate, as well as cuneane derivatives, have also been studied.Results are discussed in terms of strain relief calculated by the molecular mechanics method for cubane-like structures.
