Monosubstituted phosphinic acids can be esterified with orthosilicates in excellent yields. Whereas phosphinylidene-containing acids react selectively, disubstituted phosphinic acids and phosphonic acids remain unchanged. This method provides a convenient and general alternative to more commonly employed reactions with diazomethane or carbodiimide.
