The photolysis of α-alkoxycyclohexanones and α-alkoxycyclopentanones in ethanol involves NII elimination of an alkoxy group. The proportion of cyclanone is higher when starting from α-alkoxycyclohexanones, and esters are isolated in low yields. No ester, but aldehydes are obtained from α-alkoxycyclopentanones. By photolysis of 2-methoxy norbornanone, only epimerisation is detected. Oxetanols are formed
α-烷氧基环己酮和α-烷氧基环戊酮在乙醇中的光解涉及NII消除烷氧基。从α-烷氧基环己酮开始,环烷酮的比例较高,并且酯的分离产率低。没有酯,但是醛是从α-烷氧基环戊烷获得的。通过2-甲氧基降冰片烷酮的光解,仅检测到差向异构。仅由芳族酮,例如α-甲氧基四氢萘酮或α-甲氧基茚满酮,以令人满意的产率形成氧杂环丁烷。讨论了机械方面,包括激发态的性质。
