Thioxanthone: A Powerful Photocatalyst for Organic Reactions

and catalysis. In general, aromatic ketones constitute key players in this type of catalysis as they are involved in a plethora of examples in literature. A prime example of these types of molecules is thioxanthone (TX). In this review, we will discuss the photophysical properties of this small organic molecule, as well as the numerous examples of reactions, where it is employed as a mediator in photochemical reactions.
