Abstract
Over the last decade, visible light photocatalysis has dramatically increased the arsenal of methods for organic synthesis and changed the way we activate molecules for chemical reactions. Polypyridyl transition metal complexes, redox-active organic dyes, and inorganic semiconductors are typically used as photocatalysts for such transformations. This chapter reviews the applications of radical anions and anions as photosensitizers in visible light photoredox catalysis.
