Photoredox Catalysis with Visible Light

On the sunny side: Recent examples of visible-light-promoted photoredox catalysis in the presence of [Ru(bpy)3]2+ as an efficient photocatalyst have set new standards for conducting challenging reactions under mild and environmentally benign conditions. The increasing need for more efficient synthetic methods and sustainable processes can be seen as a major driving force for new inventions; it also stimulates the creative rethinking of known concepts, which, in turn, will lead to the development of innovative chemistry.1 For example, starting from the challenge to mimic and understand enzymatic transformations, organocatalysis has now become an important tool in modern organic synthesis with new reactivity…
