Cooperative Photoredox Catalysis Under Confinement. [PDF]

Chemistry
AbstractPhotoredox catalysis has emerged as a potent means to conduct synthetic chemistry. Leveraging light to achieve challenging organic transformations has led to many developments, both of fundamental and industrial nature. Despite their potency, photoredox processes are inherently diffusion controlled, which can limit their ability to enable both ...
