Abstract
This chapter describes representative examples of the photocatalytic fluorination and di- and trifluoromethylation of organic compounds mediated by metal complexes or metal oxides. These photocatalytic methods are useful for the synthesis of organofluorine compounds. The fundamental reaction design in each of the transformations is discussed, and general experimental procedures are included. Synthetic methodologies that involve defluorination processes or the incorporation of other fluorinated motifs are not considered in this chapter.
