Metal-free C-Se cross-couplings the formation of electron-donor-acceptor (EDA) complexes have been developed. The visible-light induced reactions can be applied for the synthesis of a series of unsymmetrical diaryl selenides employing aryl bromides, aryl iodides as well as aryl chlorides under mild reaction conditions. The scale-up was readily achieved. UV-Vis spectroscopy measurements provide insight into the reaction mechanism.
无金属 C-Se 交叉偶联反应——电子给体-受体（EDA）配合物的形成——已经被开发出来。可见光诱导的反应可以在温和的反应条件下，应用于一系列不对称二芳基硒醚的合成，使用芳基溴化物、芳基碘化物和芳基氯化物作为原料。该反应可以很容易地放大规模。紫外可见光谱测量提供了对反应机理的深入了解。
