Abstract
Photocatalytic oxygenation of benzene to phenol occurs under visible-light irradiation of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) in an oxygen-saturated acetonitrile solution of benzene and tert-butyl nitrite. The photocatalytic reaction is initiated by photoinduced electron transfer from benzene to the triplet excited state of DDQ.
摘要
在氧气饱和的苯和叔丁基亚硝酸盐的乙腈溶液中，在 2,3-二氯-5,6-二氰基对苯醌（DDQ）的可见光照射下，苯发生光催化氧化生成苯酚。光催化反应是由苯向 DDQ 的三重激发态的光致电子转移引发的。
