- 中文摘要: Upon irradiation in 2-propanol, p-nitroacetophenone 1 was reduced via the triplet state to p-hydroxyaminoacetophenone 5 which was further reduced to p-aminoacetophenone 2 and 4,4’-diacetylazobenzene 4. Similar irradiation of 5 also gave 2 and 4, and its oxidation by oxygen gave 4,4’-diacetylazoxybenzene 3. photolysis of monomeric p-nitrosoacetophenone 6 afforded acetophenone and 3 that were not produced during the irradiation of 1. Possible photoreaction pathways were discussed on the basis of published mechanisms.
