The reactions of cyclopentadiene with cyclohexa-2,4-dienones of general structure (VII) have been shown to proceed by initial diene addition of the hydrocarbon to the 4,5-double bond of the cyclohexadienone. The resulting adducts, which are derivatives of tricyclo[6,2,1,0]undeca-5,9-dien-4-one (III), rearrange even at room temperature to give products having the tricyclo[5,2,2,0]undeca-4,10-dien-8-one
已经表明,环戊二烯与通式(VII)的环己-2,4-二烯酮的反应是通过将烃最初二烯加成到环己二烯酮的4,5-双键上而进行的。所得的加合物是三环[6,2,1,0] undeca-5,9-dien-4-one(III)的衍生物,甚至在室温下也可重排,得到具有三环[5,2,2的产物,0] undeca-4,10-dien-8-骨架(I),但是它们的中间性已经通过叠氮化苯的诱捕实验得到证实。
