    Description / Table of Contents: Organische Derivate des Zinns. III. Reaktionen des Trialkylzinnäthoxids mit Aminoalkoholen.Die Reaktionen von Tributylzinnäthoxid, Bu3SnOC2H5, mit N,N-Dialkylaminoalkoholen ergeben Bu3SnORNR2- (R = s. Abstract). Bei Reaktionen von Bu3SnOC2H5 mit N-Methyläthanolamin, HOCH2 · CH2NHMe, und verschiedenen Aminoalkoholen, HORNH2 (R = s.Abstract) reagieren sowohl Hydroxyl- wie auch Aminogruppen unter Bildung von Verbindungen wie Bu3SnOCH2 · CH2NHMe, Bu3SnOCH2 · CH2NMeSnBu3, Bu3SnO · R · NH2, Bu3SnO · R · NH · SnBu3 bzw. Bu3SnO · R · N(SnBu3)2. Mit o-Aminophenol wird nur Bu3SnO · C6H4NH2 gebildet.
    Notes: The reactions oi tributyltin ethoxide, Bu3SnOEt, with N,N-dialkylalkanolamines, HORNR2 (where R = —CH2 · CH2—, —CH2 · CH2 · CH2— and —CH2 · MeCH—; R = —CH3 and —C2H5) give Bu3SnORNR2. In reactions of Bu3SnOEt with N-methylethanolamine, HOCH2 · CH2NHMe, and various alkanolamines, HO · R · NH2, (where R = —CH2 · CH2— —CH2 · CH2 · CH2—, —CHMe · CH2— —CH2 · Me2C— and —CH2 · CH · CH2 · Me) both the hydroxy as well as the amino groups show reactivity to form products of the type: Bu3SnOCH2 · CH2NHMe, Bu3SnOCH2 · CH2NMeSnBu3, Bu3SnO · R · NH2, Bu3SnO · R · NHSnBu3, and Bu3SnO · R · N(SnBu3)2, respectively. The reaction between Bu3SnOEt and o-aminophenol yields only Bu3SnO · C6H4NH2.

    Notes: An analysis of the Raman and infrared spectra of di-potassium tartrate hemi-hydrate (DKT), K2C4H4O6·½H2O, is reported. It has been inferred that the C4H4O62- ion and H2O molecule in a DKT crystal occupy points of C1 site symmetry. Various units of C4H4O62- ion/(H2O molecule) located at crystallographically distinguishable positions in this crystal do not appear to be different in their structure or the force fields governing their vibrational dynamics.
