Recent Advances in Transition-Metal Catalyzed C—H Bond Fluorination

Abstract

Abstract Organofluorine compounds are widely found in pharmaceuticals, agrochemicals, and materials due to their special properties. However, development of transformations to incorporate fluorine atom is usually a great challenge, because of its highly electronegative nature. Transition-metal catalyzed C—H bond fluorination has significant advantages in atom-economy, reaction diversity and environmental friendliness in comparison with the traditional transition-metal catalyzed cross-coupling approaches since it obviates the use of pre-functionalized substrates. In the past decade, C—H bond fluorination strategy has emerged as a powerful protocol to access new C—F bonds. This review presents the state of art for transition-metal catalyzed C—H bond fluorination. The existing problems and limitations of the field are summarized and the outlook of the area is also prospected.
