    Description / Table of Contents: Diphenyl-bis(P-trimethylphosphinimino)-phosphonium ChlorideThe reaction of Na⊕(CH3)3Si—N—P(C6H5)2—N—Si(CH3)3⊖ III with (CH3)3PCI2 results in the elimination of NaCI and (CH3)3SiCI and the formation of (CH3)3P = N—P(C6H5)2—N = P(CH3)3 ⊕CI⊖ VII. The mechanism of the reaction is discussed. (CH3)3P = N—P(C6H5)2 = N—Si(CH3)3 V can be obtained as an intermediate. This intermediate, when synthesized by an other independent route, is found to react with (CH3)3PCI2 to give the same product VII.
    Notes: Die Umsetzung von Na⊕(CH3)3Si—N—P(C6H5)2=N—Si(CH3)3⊖ III mit (CH3)3PCI2 führt unter NaCI- und (CH3)3SiCI-Abspaltung zu (CH3)3P = N—P (C6H5)2—N = P(CH3)3⊕CI⊖ VII. Der Reaktionsmechanismus wird diskutiert. Als Zwischenprodukt läßt sich (CH3)3P = N— P(C6H5)2 = N—Si(CH3)3 V isolieren. Es wird gezeigt, daß ein auf einem unabhängigen Weg synthetisiertes V mit (CH3)3PCI2 ebenfalls zu VII abreagiert.

    Organoblei- und Organozinnderivate von Mercaptoaminosäuren und Cysteamin (1980)

    Description / Table of Contents: Organolead and Organotin Derivatives of Mercaptoaminoacids and CysteaminReaction of tri- and diorganolead and -tin hydroxides and oxides with mercaptoaminoacids and cysteamine in CHCl3 or CHCl3/H2O allows the gentle preparation of the above compounds. The bonding between M and ligand indicated in the formula of the compounds, mainly the preferred bonding of M to S follows from vibrational spectra; proposals regarding the structure are made using spectral data. Ph3SnOH and penicillamine react to give monomeric Ph3SnSCMe2CH(NH2)COOSnPh3.
    Notes: Die Umsetzung von Tri- und Diorganoblei-und -zinnhydroxiden bzw. -oxiden mit Mercaptoaminosäuren sowie mit Cysteamin in CHCl3 bzw. CHCl3/H2O ermöglicht die schonende Darstellung von Ph3MSCH2CH(NH2)COOH, Ph3PbSCMe2CH(NH2)COOH, Ph3MSCH2CH2NH2, Me3SnSCR2′CH(NH2)COOH, Ph2M[SCR2′CH(NH2)COOH]2, Me2Sn[SCR2′CH(NH2)COOH]2, R2SnSCR2′CH(NH2)COO,Ph2MSCR2′CH(NH2)COO,Ph2M(SCH2CH2NH2)2 und Me2Sn(SCH2CH2NH2)2 (M=Pb, Sn; R′=H, Me; R=Me, Ph; Me=CH3; Ph=C6H5).Die in den Formeln der Verbindungen angezeigte Art der Bindung zwischen M und Ligand, insbesondere die bevorzugte Bindung von M an S, folgt aus den Schwingungsspektren, mit deren Hilfe auch Strukturvorschläge diskutiert werden. Ph3SnOH reagiert mit Penicillamin zu monomerem Ph3SnSCMe2CH(NH2)COOSnPh3.
