Ruthenium(II) polypyridyl complexes promote the efficient radicalcation Diels-Alder cycloaddition of electron-rich dienophiles upon irradiation with visible light. These reactions enable facile [4 + 2] cycloadditions that would be electronically mismatched under thermal conditions. Key to the success of this methodology is the availability of ligand-modified ruthenium complexes that enable rational
钌 (II) 多吡啶基配合物在可见光照射下促进富电子亲二烯体的有效自由基阳离子 Diels-Alder 环加成反应。这些反应使 [4 + 2] 环加成能够在热条件下发生电子失配。这种方法成功的关键是配体修饰的钌配合物的可用性,这些配合物能够合理调整催化剂的电化学性能,而不会显着扰乱系统的整体光物理性能。
