钌(II)多吡啶配合物在可见光照射下促进富电子二亲化合物的有效自由基阳离子Diels-Alder环加成。这些反应使在热条件下电子不匹配的[4+2]环加成成为可能。该方法成功的关键在于配体修饰的钌配合物的可用性,这种配合物能够在不显著干扰系统整体光物理性质的情况下合理调整催化剂的电化学性质。
Ruthenium(II) polypyridyl complexes promote the efficient radical cation 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 the rational tuning of electrochemical properties of the catalyst without significantly perturbing the overall photophysical properties of the system.
