Domino C–Se cross-coupling of 2-(iodoaryl)selenoureas with aryl iodides has been accomplished in the presence of a copper(I)–1,1-phenanthroline complex at moderate temperature. The reactions involve intra- and intermolecular C–Se cross-coupling to give the substituted 2-(arylselanyl)arylcyanamides. Aryl iodides having electron-donating and -withdrawing substituents are compatible, affording the targetselanyl
2-(碘芳基)硒脲与芳基碘化物的多米诺 C-Se 交叉偶联已在铜 (I)-1,1-菲咯啉配合物的存在下在中等温度下完成。该反应涉及分子内和分子间 C-Se 交叉偶联以产生取代的 2-(芳基硒基)芳基氰胺。具有给电子和吸电子取代基的芳基碘是相容的,以高产率提供目标硒基醚。
