Follow the guide: The palladium‐catalyzed phosphonation of a C(sp2)H bond occurs through the use of a pyridyl group as the directing group. α‐Hydroxyalkylphosphonate is used as the phosphonating reagent (see scheme).
catalyzed C-H phosphorylation remains an unsolved challenge. Reported methods are generally limited in scope and require stoichiometric silver salts as oxidants. Reported here is an electrochemically driven RhIII -catalyzedarylC-H phosphorylation reaction that proceeds through H2 evolution, obviating the need for stoichiometric metal oxidants. The method is compatible with a variety of arylC-H and P-H
