Recent Advances in the Photocatalytic Defluorinative Functionalization of Trifluoromethyl Arenes and Trifluoromethyl Ketones via Radical Process

Recent years have witnessed a rapid growth in the C‐F bond functionalization of trifluoromethylarenes and trifluoromethyl carbonyl compounds, which was promoted by the development of photoredox catalysis. In this review, the photocatalyzed C‐F bond activation of trifluoromethylarenes and trifluoromethyl carbonyl compounds via difluoromethyl radical intermediate has been covered. This review was categorized into three parts based on the activation modes of C‐F bond. Several representative instances, in conjunction with the reaction mechanism, were also deliberated upon.
