    Description / Table of Contents: Synthesis and Spectroscopic Studies of Di-t-butyltin(IV) dicarboxylatesFive Di-t-butyltin(IV) dicarboxylates t-Bu2Sn(O2CR)2 (R = CH3, C(CH3)3, C6H5, C6H4NH2-2, C5H4N-2) have been synthesized by reaction of Di-t-butyltinoxide (t-Bu2SnO)3 with corresponding ligands and studied by 1H-, 13C-, 119Sn n.m.r. and infrared spectroscopy.The compounds are monomeric in CD2Cl2- or CDCl3-solution and have pentacoordinated tin atoms with exception of the picolinate. The coordination takes place through the carboxylic oxygen atoms. In the Di-t-butyltin(IV)di-2-picolinate the tin atom is hexacoordinated by intramolecular tin-nitrogen-interaction.
    Notes: Durch Reaktion von Di-t-Butylzinnoxid (t-Bu2SnO)3 mit dem entsprechenden Liganden wurden fünf Di-t-Butylzinn(IV)-dicarboxylate t-Bu2Sn(O2CR)2 (R = CH3, C(CH3)3, C6H5, C6H4NH2-2, C5H4N-2) hergestellt und 1H-, 13C-, 119Sn-NMR- und IR-spektroskopisch untersucht.Die Substanzen sind in CD2Cl2- bzw. CDCl3-Lösung monomer und besitzen mit Ausnahme des Picolinats pentakoordiniertes Zinn, wobei die Koordination über den Carbonylsauerstoff erfolgt. Im Di-t-Butylzinn(IV)-di-2-picolinat ist das Zinnatom dagegen durch intramolekulare Zinn-Stickstoff-Wechselwirkung hexakoordiniert.
