Eine neue einfache Methode zur Entalkylierung von Phosphon- und Phosphinsäureestern

A New Facile Method for the Dealkylation of Phosphonic and Phosphinic Acid Esters The synthesis of phosphonic and phosphinic acid esters of the type is realized by reaction of dialkylphosphonates and O-alkylphosphinates with chlorotrimethylsilane in the presence of catalytical amounts of NH₄Cl and hexamethyldisilazane (HMDZ).
