Organophosphorus compounds are of great significance in organic chemistry. Therefore, the construction of phosphorus-containing compounds has attracted significant attention from organic chemists. Radical phosphorylation has become a powerful strategy for building organophosphorus compounds and numerous achievements have been realized in recent years. In this review, we summarize the development of the generation and application of phosphorus radicals in organic chemistry since 2016. Special emphasis is given to various new transformations involving the generation of P-centered radicals via transition metal catalytic, photochemical and electrochemical means. Recent advances in the development of metal-free catalytic phosphorylations involving Pcentered radicals are also reviewed.

In this letter, we successfully explored a cascade Pd/Cu-catalyzed intermolecular C­(sp3)–H arylation of amides and intramolecular C–N coupling reaction. This method provides a one-pot strategy to synthesize 3,4-2H-quinolinone with good regioselectivity of C–H arylation and C–N coupling from C–I and C–X bonds from readily available starting materials.
