Recherches sur la formation et la transformation des esters LXXIII Sur la préparation d'acides ω-[aryl (ou aralcoyl ou alcoyl) carbamylamino]-alcoylphosphoriques et sur leur vitesse de scission à divers pH

N-Aryl(or aralkyl or alkyl)carbamoyl-aminoalkyl phosphoric monoesters have been prepared by the reaction of isocyanates R′-N?C?O on the corresponding amino-alkylphosphoric monoesters H₂N? R? OPO₃H₂ in the presence of 2 equivalents of NaOH. The rates of scission of the phosphoric monoester group and occasionally of the phenylcarbamoylamino group of these monoesters have been studied at 100°, in solutions 0.1M in ester and at various pH.
