carboxamides are irradiated in a basic medium. On the basis of photochemical and photophysical experiments, we propose that 2-indolylbenzoxazole is formed by intramolecular electron transfer followed by fast dehalogenation of the halophenyl radical anion pendant moiety, finally a radical–radical collapse renders the observed product.
当在碱性介质中辐照N-(2-卤代苯基)吲哚羧酰胺时,可获得O-酰化反应。在光化学和光物理实验的基础上,我们提出2-吲哚基苯并恶唑是通过分子内电子转移然后卤代苯基自由基阴离子侧基部分快速脱卤而形成的,最后自由基-自由基的塌陷提供了观察到的产物。
