    Description / Table of Contents: Ligand Structure and Complexation, XLV. - New Crown Ether EstersThe synthesis and properties of the new cyclic and non-cyclic crown ether type ligands 1-15 are described. They contain carboxylic and squaric ester units. Their ligand character has been proven by isolating crystalline complexes with sodium and potassium salts. With KSCN, 15 does not yield the expected ester complex (18), but the complex 19 of the diphenol 17.
    Notes: Synthese und Eigenschaften der neuen cyclischen und offenkettigen Neutralliganden 1-15 des Kronenethertyps, die Carbonsäure-oder Quadratsäureester-Gruppen enthalten, werden beschrieben. Die Ligandeigenschaften wurden durch Isolierung kristalliner Komplexe mit Natrium- und Kaliumsalzen nachgewiesen. 15 liefert mit KSCN nicht den erwarteten Komplex 18 des Esters, sondern den Komplex 19 des Diphenols 17.
