Abstract:

With the progress of positron emission tomography(PET), the study of efficient 18F-labeling reactions is of great value. Meanwhile, with the rapid development of organic fluorine chemistry, researchers have developed a series of reagents as C1 synthons to yield difluoromethyl radical(·CHF2), which can be introduced into the 18F- labeling reactions. In this review, we analyzed from the perspective of chemical principles and summarized the recent studies on ·CHF2 synthons, C—H bond activation and related 18F-labeling reactions. Furthermore, the research trends and hotspots were discussed.

Key words: Difluoromethyl radical(·CHF2), C—H Bond activation, 18F-labeling, Positron emission tomography
