Ideal chemical transformations in terms of green and sustainable chemistry convert abundant, low energy starting materials into high value products without losing a single atom.1 Light-driven catalysis offers tools for such reactions.2 We discuss in the lecture key photocatalytic principles and how they can be applied to redox-neutral reactions, such as C-H carboxylations of alkanes and arenes with carbon dioxide.3 Current scope and limitations are shown and a perspective is given where the use of light may lead to better catalysis.4
