A reaction of aromatic halides bearing electron-withdrawing groups with tertiary amines in the presence of an iridium catalyst under blue light irradiation is described. Products of the aromatic substitution of the halide by the dialkylamino fragment are obtained. The interaction of aryl radicals with tertiary amines to generate zwitterionic radical species is believed to be the key factor responsible
描述了带有吸电子基团的芳香族卤化物与叔胺在铱催化剂存在下在蓝光照射下的反应。获得卤化物被二烷基氨基片段芳族取代的产物。芳基自由基与叔胺相互作用产生两性离子自由基物种被认为是影响反应效率的关键因素。
