Abstract
Carbon-fluorine bond formations have received a lot of attention because organofluorine compounds are widely used in pharmaceutical, agricultural, and materials science applications. In particular, the incorporation of fluorine-18, which is a commonly used radioisotope for radiopharmaceuticals for positron emission tomography (PET), a molecular imaging tool for the visualization of biochemical events, human metabolism processes, and the measurement and diagnosis of diseases in humans, plays a crucial role in clinical and preclinical studies. Several synthetic methodologies for carbon-fluorine-18 bond formation have been developed. However, conventional fluorination methods have some remaining drawbacks such as the high temperature and basic environment. Photo-induced catalysis is an emerging technique that allow chemists to achieve the synthesis of target molecular architectures under mild conditions. Moreover, several radiofluorination strategies have been developed via photocatalysis. In this review, we focused on describing recent advances in the field of light-mediated radiofluorination.
