    Description / Table of Contents: Synthesis of 2- or 3-substituted Alkanediphosphonic AcidsSyntheses of substances of the general formula RCX(PO3H2)2 X = OH, H, Cl, NH2 have been known for a long time. The preparative possibilities for the synthesis of alkanediphosphonic acids containing an amino group or a chlorine atom in the 2- or 3-position were limited, only 2 substances from this class of compounds being known. Further examples of this class of substances have been synthesized.
    Notes: Synthesen von Verbindungen der allgemeinen Formel RCX(PO3H2)2 X = OH, H, Cl, NH2 sind seit langem bekannt. Begrenzt sind die Herstellungsmöglichkeiten von in 2- oder 3-Stellung Aminogruppen- bzw. Chlor-enthaltenden Alkandiphosphonsäuren, so daß bisher erst zwei Vertreter dieser Körperklasse beschrieben wurden. Es gelang, eine Reihe weiterer Verbindungen dieser Struktur zu synthetisieren.

    Description / Table of Contents: Reactions of Benzoylating Agents with Phosphorous AcidH3PO3 reacts with (C6H5CO)2O to yield C6H5C(OH)(PO3H2)2 1. In contrast, the reaction with C6H5COCl proceeds with the formation of C6H5CCl(PO3H2)2 2 and p-ClC6H4CH(PO3H2)2 3. The best yields of 2 and 3 are obtained, if the reaction are carried out under pressure. 2 is rapidly hydrolysed in alkaline solution at elevated temperatures to 1.
    Notes: H3PO3 reagiert mit (C6H5CO)2O zu C6H5C(OH)(PO3H2)2 1, mit C6H5COCl dagegen zu C6H5CCl(PO3H2)2 2 und p-ClC6H4CH(PO3H2)2 3. Die besten Ausbeuten an 2 und 3 werden im Autoklaven erzielt. 2 hydrolysiert in alkalischer Lösung in der Hitze schnell zu 1.

    Description / Table of Contents: Syntheses of Phosphono-carboxylic Acids by Michael AdditionA number of phosphono-carboxylic acid esters are available by means of alkaline catalytic addition of P—H and C—H acidic esters to activated double and triple bonds. These may be transformed into complexing agents by hydrolysis.
    Notes: Durch alkalisch katalysierte Addition P—H- bzw. C—H-acider Ester an aktivierte Mehrfachbindungen ist eine Reihe von Phosphonocarbonsäureester zugänglich. Diese werden durch Verseifung in Komplexbildner überführt.

    Description / Table of Contents: Reactions of 1-Aminoalkane-1,1-diphosphonic Acids with Nitrous AcidCompounds of the structure RC(NH2)(PO3H2)2 1 give products RC(OH)(PO3H2)2 2 in high yields by the reaction with nitrous acid. In contrast, when R = Aryl the reaction of 1 often gives in concentrated hydrochloric acid RCCl(PO3H2)2 3. Exceptions to the above reaction are described.
    Notes: Verbindungen der Struktur RC(NH2)(PO3H2)2 1 reagieren mit salpetriger Säure meist in sehr hoher Ausbeute zu RC(OH)(PO3H2)2 2. Für R = Aryl reagiert 1 in stark salzsaurer Lösung dagegen oft zu RCCl(PO3H2)2 3. Einige Ausnahmen der obigen Reaktionen werden behandelt.
