| 摘 要： | 对于容易发生单线态氧(^1O2)反应的稠环烯烃能否在氰基蒽敏化下发生电子转移光氧化研究甚少. 作者曾报道了氰基蒽敏化的9-本甲叉芴的ET光氧化过程. 本文首次探讨了非交替稠环烃, 苊烯(AN), 在9,10-二氰蒽(DCA)或9-氰基蒽(CNA)敏化下的光氧化反应及其机理.

| Abstract: | The photooxidn. of acenaphthylene (AN) sensitized by 9,10-dicyanoanthracene (DCA) or 9-cyanoanthracene in acetonitrile was shown to give carbonyl-contg. derivatives I-IV. It was found that the reaction proceeded in a stepwise manner and the dimerization of AN competed with the photooxidn. An electron-transfer (ET) mechanism which involves 2-step ET accounted for the title reaction. It was shown that biphenyl (BP) could considerably enhance the above photooxidn. The behavior of BP corresponds to inserting an ET relay chain in the initial DCA-sensitized chains. |
