The photolysis of trans-β-methylstyrene oxide proceeds smoothly, but neither the corresponding cis-isomer nor β,β-dimethylstyrene oxide are photochemically active. Moreover, although styrene glycol carbonate undergoes photolysis to extrude carbon dioxide, the β,β-dimethylstyrene glycol carbonate is photochemically unreactive. These results are explained by looking at the energies required to obtain
反式-β-甲基苯乙烯氧化物的光解进展顺利,但相应的顺式异构体和β,β-二甲基苯乙烯氧化物均无光化学活性。此外,尽管碳酸苯乙烯乙二醇酯经历光解以挤出二氧化碳,但是β,β-二甲基苯乙烯乙二醇碳酸酯在光化学上不反应。通过查看获得构象所需的能量来解释这些结果,在构象中,芳环的平面与环氧化物部分的轨道正交。
