A photoinduced iron-catalyzed ipso-nitration of aryl halides with KNO2 has been developed, in which aryl iodides, bromides, and some of aryl chlorides are feasible. The mechanism investigations show that the in situ formed iron complex by FeSO4, KNO2, and 1,10-phenanthroline acts as the light-harvesting photocatalyst with a longer lifetime of the excited state, and the reaction undergoes a photoinduced
光致铁-催化的本位与KNO芳基卤化物的-nitration 2已经被开发出来,其中的芳基碘化物,溴化物和某些芳基氯化物的是可行的。机理研究表明,FeSO 4、KNO 2和1,10-菲咯啉原位形成的铁络合物作为捕光光催化剂,激发态寿命更长,反应发生光诱导单电子转移(SET) 过程。这项工作代表了光诱导铁催化的 Ullmann 型耦合的一个例子。
