Oxidative Phoshonylation of Aromatics with Ammonium Cerium(IV) Nitrate

Article abstract of DOI:10.1055/s-1987-28077

Arylphosphonates 5 and 6 can be prepared in good yields in a one-step synthesis starting from arenes with tri- or diethylphosphites and cerium ammonium nitrate (CAN) as oxidant.The seletivity of the oxidative phosphonylation is relatively low; the reactive species is a phosphite radical cation.
