众所周知，钌（II）多吡啶配合物的光氧化还原催化是合成有机化学中氧化还原反应的通用工具，因为它们可以通过可见光照射有效地催化单电子转移（SET）过程。催化剂的这些优良性质为高效选择性自由基反应提供了一种新的策略。三（2,2′-联吡啶）钌（II）盐[Ru(bpy)3]2+于1936年首次报道。此后，有关人工光合作用和光功能材料的研究工作陆续报道，但在合成有机化学方面的研究却十分有限。值得注意的是，自2008年以来，这种光催化系统在氧化还原反应中发挥了重要作用。在这一章中，我们将简要回顾2008年前后在钌光氧化还原催化方面的重要工作，然后介绍我们最近在光氧化还原催化烯烃三氟甲基化方面的研究课题。
Photoredox catalysis by well-known ruthenium(II) polypyridine complexes is a versatile tool for redox reactions in synthetic organic chemistry, because they can effectively catalyze single-electron-transfer (SET) processes by irradiation with visible light. These favorable properties of the catalysts provide a new strategy for efficient and selective radical reactions. Salts of tris(2,2′-bipyridine)ruthenium(II), [Ru(bpy)3]2+, were first reported in 1936. Since then, a number of works related to artificial photosynthesis and photofunctional materials have been reported, but only limited efforts had been devoted to synthetic organic chemistry. Remarkably, since 2008, this photocatalytic system has gained importance in redox reactions. In this chapter, we will present a concise review of seminal works on ruthenium photoredox catalysis around 2008, which will be followed by our recent research topics on trifluoromethylation of alkenes by photoredox catalysis.
