    Description / Table of Contents: Synthesis of Phosphoric Acid Ester Chlorides, Phosphinic Acid Chlorides, Diphosphoric Acid Tetraesters, and Phosphinic Acid Anhydrides by Action of the System Triphenylphosphine/Carbon Tetrachloride on Phosphoric Acid Esters and Phosphinic AcidsPhosphoric acid mono- and diesters and phosphinic acids react with triphenylphosphine/carbon tetrachloride to acid chlorides or corresponding acid anhydrides. In presence of triethylamine only acid anhydrides can be obtained.
    Notes: Phosphorsäurehalbester und Phosphinsäuren reagieren mit dem Reagenz Triphenylphosphin/Tetrachlorkohlenstoff teilweise zu Säurechloriden, teils auch zu den betreffenden Säureanhydriden. In Gegenwart von Triäthylamin erfolgt stets die Bildung von Säureanhydriden.

    Description / Table of Contents: A New Synthesis of Phosphoric Acid Ester Amides, Phosphinic Acid Amides, Phosphinic Acid Esters and Mixed Substituted Phosphoric Acid TriestersThe system triphenylphosphine/carbon tetrachloride may be used as a dehydrating agent for the intermolecular amide and ester condensation of phosphoric acid mono- or diesters and phosphinic acids. Conveniently the process is carried out as a simultaneous reaction at room temperature with the four components phosphoric acid/phosphine/carbon tetrachloride/amine (alcohol).
    Notes: Das System Triphenylphosphin/Tetrachlorkohlenstoff läßt sich als Dehydratisierungsreagenz für die intermolekulare Amid- und Esterkondensation von Phosphorsäurehalbestern und Phosphinsäuren verwenden. Das Verfahren kann bei Raumtemperatur bequem als Eintopfreaktion mit den 4 Komponenten Phosphorsäure/Phosphin/Tetrachlorkohlenstoff/Amin (Alkohol) durchgeführt werden.
