化学家们一直渴望像植物那样合成分子--利用阳光来促进复杂分子结构的构建。然而，在光化学合成中使用可见光从根本上是具有挑战性的，因为有机分子倾向于不与在太阳光谱中最强烈发射的可见光的波长相互作用。最近的研究已经开始利用吸收可见光的过渡金属络合物催化广泛的合成有价值的反应的能力。在这篇综述中，我们强调了如何理解这些过渡金属络合物的光催化活化机制，以及通过可见光照射可获得的中间体的一般反应模式，加速了这一系列不同反应的发展。
Chemists have long aspired to synthesize molecules the way that plants do — using sunlight to facilitate the construction of complex molecular architectures. Nevertheless, the use of visible light in photochemical synthesis is fundamentally challenging because organic molecules tend not to interact with the wavelengths of visible light that are most strongly emitted in the solar spectrum. Recent research has begun to leverage the ability of visible light absorbing transition metal complexes to catalyze a broad range of synthetically valuable reactions. In this review, we highlight how an understanding of the mechanisms of photocatalytic activation available to these transition metal complexes, and of the general reactivity patterns of the intermediates accessible via visible light photocatalysis, has accelerated the development of this diverse suite of reactions.
