efficient phosphorylation of C(sp3)–H bonds of arenes with diaryl phosphinic acids via Bu4NI-catalyzed dehydrogenativecoupling has been developed. This transformation proceeds efficiently under transition-metal-free reaction conditions and represents a straightforward method to prepare valuable organophosphorus compounds from readily available arenes and diaryl phosphinic acids.

the iodination reagent under transition‐metal‐free conditions. The present protocol is compatible with different functional groups, and suitable for various alkenes and P(O)−OH compounds. A variety of functionalized β‐iodo‐1‐ethyl phosphinic/phosphoric acid esters are obtained in good to excellent yields, which could be further transformed to diversified building blocks for the synthesis of bioactive

A copper-catalyzed diphenylation of P(O)-OH bonds with cyclic diaryliodonium salts is described. Valuable 2'-iodo substituted biaryl phosphinic/phosphoric acid esters were obtained in good to excellent yields, which could be further transformed to diversified building blocks for the synthesis of bioactive compounds, pharmaceuticals and functional materials.
