The photochemical reactions of cycloheptatriene with p-benzoquinone and 1,4-naphthoquinone yielded the spirocyclic ethers, which had 7-oxabicyclo[4.2.1]nona-2,4-diene structures, by the characteristic (6+2)π cycloaddition process. The latter quinone further produced the carbocyclic (2+2)π and (6+2)π cycloadducts.
环庚三烯与对苯醌和 1,4-萘醌的光化学反应通过特征性的 (6+2)π 环加成过程产生具有 7-氧杂双环 [4.2.1]nona-2,4-二烯结构的螺环醚. 后一种醌进一步产生碳环 (2+2)π 和 (6+2)π 环加合物。
