Synthesis of new functionalized hydroxy‐ and aminomethylphosphinates with indan moieties.

Abstract: The convenient synthesis of new functionalized organophosphorus acids and their derivatives containing indan moieties was developed. The regioselective radical addition of bis(trimethylsiloxy)phosphine to indene proceeds to give rise to 2‐indanylphosphonite as key compound for preparation of above acids with bicyclic substituents. Azobis(isobutyronitrile) (AIBN) in the conditions of its thermolysis was used as effective initiator of the addition reaction. The further treatment of organophosphorus acids trimethylsilyl esters with the methanolic sodium methoxide solution resulted in the water‐soluble sodium salts of the corresponding acids.
