Recent advances in photochemical construction of aromatic C-P bonds via C-hetero bond cleavage.

Photochemical synthesis is flourishing in recent years, which has provided new and efficient methods for aromatic C-P bond formation. This review summarises the recent advances in photochemical C-P bond cross-couplings in aromatics, enriching the synthetic methods of phosphorus containing compounds. Photosensitizer-catalyzed and photosensitizer-free reactions are reviewed. Different types of bond cleavages for substrates, such as C-X (X = F, Cl, Br, I), C-N and C-O bond cleavage, are discussed in three categories.
