A photosensitizer [Ru(bpy)3]2+ catalyzes oxidative coupling reaction of enamines with silyl enol ethers under visible light irradiation by a Xe lamp or sunlight to produce γ-diketones. A 2e-oxidation process involved in this reaction is achieved by a combination of the photoexcited [Ru(bpy)3]2+ species and duroquinone, a 2e-acceptor.
一种光敏剂 [Ru(bpy)3]2+ 在可见光照射下(通过
氙灯或阳光)催化烯胺与
硅醇醚的氧化偶联反应,生成 γ-二酮。该反应中涉及的 2e-氧化过程是通过光激发的 [Ru(bpy)3]2+ 物种与 2e-接受体杜罗醌的结合实现的。
