在综述的反应中，有机分子在辐射下催化化学反应。活化是基于氢或电子转移。常用的光有机催化剂有芳香酮、醌、杂环、染料;形成的中间体是自由基、自由基离子和来自前体如烷烃、烯烃、胺、醚等的离子。（主要是氧化）和还原过程与胺和酮的α-官能化，共轭加成，该方法的主要特点是在温和的条件下顺利生成高活性中间体。
In the reactions reviewed, an organic molecule under irradiation catalyzes a chemical reaction. The activation is based either on hydrogen or on electron transfer. Commonly used photoorganocatalysts are aromatic ketones, quinones, heterocycles, dyes; intermediates formed are radicals, radical ions and ions from precursors such as alkanes, alkenes, amines, ethers etc. Oxidation (mainly oxygenation) and reduction processes are obtained along with the α-functionalization of amines and ketones, conjugate additions, cycloadditions etc. The key characteristic of the method is the smooth generation of highly reactive intermediates under mild conditions.
