A novel approach to phosphonic acids from hypophosphorous acid
A novel access to phosphonic acids via Pd-catalyzed tandem carbon-phosphorus bond formation-oxidation processes was developed. The procedures involve atom-economical and environmentally friendly functionalization reactions of hypophosphorous acid (H3PO2) and H-phosphinic acids [RP(O)(OH)(H)].

Palladium-catalyzed arylation of diethyl phosphonate in aqueous-organic media
Diethyl arylphosphonates were synthesized by reactions of diethyl phosphonate with aryl iodides or bromides containing electron-donor or electron-acceptor substituents in the aromatic ring in aqueous acetonitrile or neat water in the presence of palladium

Arylphosphonic acids. I. Substituent effects on their first and second dissociations
Thermodynamic pK1 and pK2 values of 36 arylphosphonic acids have been determined.The pK values of the meta and para compounds are correlated well by the ?n parameter, suggesting that there is little conjugation between the
