Photoredox catalysis has gained recent prominence due to the ability to employ mild reaction conditions and achieve challenging chemical transformations. A significant portion of this work has focused mainly on employing ruthenium andiridium polypyridyl complexes due to their characteristics as photocatalysts. However, as photocatalysis becomes morecommonplace in synthetic labs, so does the need for a more sustainable non-rare earth metal catalyst. In this seminar, the designand application of new strongly reducing photoredox catalysts are discussed with examples of their implementation in smallmolecule and macromolecular syntheses.
