由缺电子光敏剂所引起的电子转移(ET)光氧化反应目前已受到广泛注意.然而,对于容易发生单线态氧(~1O_2)反应的稠环烯烃能否在氰基蒽敏化下发生ET光氧化仍研究甚少.最近作者报道了氰基蒽敏化的9-苯甲叉芴的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. Takeshita等不久前报道,AN受玫瑰红(RB)敏化生成的~1O_2反应产物为顺或反式
Electron transfer (ET) photooxidation caused by electron-deficient photosensitizer has been widely paid attention at present.However, is it possible for the condensed cyclic olefins that are susceptible to singlet oxygen (~ 1O_2) reactions to occur under the sensitization of cyanoanthracenes Photooxidation is still poorly studied. Recently, the authors reported the photo-oxidation of cyano-anthracene sensitized 9-benzofluorene by ET photoinformation.In this paper, for the first time, the non-alternating condensed cyclic hydrocarbons, camphene (AN) Takeshita et al. Recently reported that ~ 1O 2 reaction product of AN sensitized by rosin (RB) is cis or Trans
