光可以被认为是环境友好的“绿色”化学合成的理想试剂;与许多常规试剂不同，光是无毒的，不产生废物，并且可以从可再生资源中获得。然而，在大多数有机光化学过程中需要高能紫外线辐射，这限制了光化学合成在工业相关规模上的实用性和环境效益。这一观点介绍了最近的方法，使用金属聚吡啶光催化剂在合成有机转化。考虑到这些配合物的显着物理性质，这些使用Ru（bpy）（3）（2+）和相关光催化剂的新转化可以使用几乎任何可见光源进行，包括商店购买的荧光灯泡和环境阳光。因此，过渡金属催化剂代表了一种有前途的策略，可以开发具有巨大环境效益的实用、可扩展的工业过程。
Light can be considered an ideal reagent for environmentally friendly, 'green' chemical synthesis; unlike many conventional reagents, light is non-toxic, generates no waste, and can be obtained from renewable sources. Nevertheless, the need for high-energy ultraviolet radiation in most organic photochemical processes has limited both the practicality and environmental benefits of photochemical synthesis on industrially relevant scales. This Perspective describes recent approaches to the use of metal polypyridyl photocatalysts in synthetic organic transformations. Given the remarkable photophysical properties of these complexes, these new transformations, which use Ru(bpy)(3)(2+) and related photocatalysts, can be conducted using almost any source of visible light, including both store-bought fluorescent light bulbs and ambient sunlight. Transition metal photocatalysis thus represents a promising strategy towards the development of practical, scalable industrial processes with great environmental benefits.
