The development of new photocatalytic reactions has emerged as one of the major themes of research in contemporary organic synthesis. This field relies upon the ability of photocatalysts to absorb light and use the energy to generate diverse reactive intermediates including radicals, radical ions, and triplet diradicals under mild and operationally convenient conditions.1,2 Importantly, the transformations accessible from these reactive intermediates are often distinctive and can be difficult to replicate via thermal activation. Much of the motivation for the discovery of new photocatalytic reactions, therefore, has been the ability to access new bond formations involving these reactive intermediates that have important applications in pharmaceuticals, materials chemistry, and commodity chemistry synthesis.
