반응 단계
A solution of 4-cyclopentene-1,3-dione (7.0g; 0.073 mole) in dry benzene (20ml.) was added to 1,3-cyclohexadiene (12g; 0.15 mole). After addition of a few crystals of 2,5-ditert-butyl hydroquinone the stoppered mixture was stood at room temperature for 4 days. Removal of the solid and recrystallisation from methanol gave the adduct m.p. 264°.
