    Description / Table of Contents: The First Monosubstituted Derivatives of triborane(7). - Crystal and Molecular Structure of Benzoyloxytriborane(7)B6H14 generated in situ has been shown to react with carboxylic acids, monothiocarboxylic acids, dialkoxydithiophosphorus acids, and diaryldithiophosphinic acids by splitting off H2 to form the chelate-stabilized compounds of the type B3H6X, where X = RCO2, RCOS, (RO)2PS2 und R2PS2. Reactions of carboxylic acids with some triborane(7) adducts or B4H10 produce the same type of compounds. The X-ray structure determination of Ph—CO2B3H6 is reported. All compounds show fluxional behaviour on the 11B-NMR time scale.
    Notes: Generiert man B6H14 in situ in Gegenwart von Carbonsäuren, Monothiocarbonsäuren, Dialkoxydithiophosphorsäuren oder Diaryldithiophosphinsäuren, so entstehen unter H2-Abspaltung die Chelat-stabilisierten Verbindungen des Typs B3H6X, wobei X = RCO2, RCOS, (RO)2PS2 und R2PS2 sein kann. Zum gleichen Verbindungstyp gelangt man bei der Reaktion zwischen bestimmten Triboran(7)-Addukten bzw. B4H10 mit Carbonsäuren. Von Ph—CO2B3H6 wurde eine Röntgenstrukturanalyse durchgeführt. Sämtliche Verbindungen zeigen im 11B-NMR-Spektrum dynamisches Verhalten.
