    Notes: O=As(NMe2)3 (HMAsT) is obtained in low yields by reacting O=AsCl3 with excess HNMe2 or by ozonolysis of As(NMe2)3; however, it is formed in yields 〉65% by using (Me3Si)2O2 and As(NMe2)3 in hydrocarbon solution. The structure of HMAsT was established by IR/Raman, NMR and mass spectroscopy, and single crystal X-ray structure analysis. The structure determination revealed (sp3C)-H…O-hydrogen bonding in the solid state. Acid-base reaction by methanolysis affords ionic [Me2NH2] [O2As(OMe)2] while iodide is oxidized to iodine.

    Notes: Die einfachen PMR-Spektren der Methylzinn-dimethylamide (CH3)4-nSn-[N(CH3)2]n und einiger Substitutionsprodukte aus der Reaktion mit Hexamethyldisilazan werden mitgeteilt. Es wird dabei immer nur ein Silazanrest in das Zinnamid eingeführt. Frühere Ergebnisse und obiger Befund sprechen für die Annahme eines nicht unbeträchtlichen Doppelbindungsanteiles für die Zinn-Stickstoffbindung. Für diese Deutung spricht auch die Kopplung der magnetisch aktiven Zinnisotope 117,119Sn mit den Protonen der über den Stickstoff gebundenen Methylgruppen, die bei reinen Methylzinn-dimethylamiden nicht beobachtet wurde.

    Notes: Die Dipolmomente einer Reihe von Organozinnchloriden R4-nSnCln(R = CH3, C2H5 C4H9, C6H5) deuten auf eine Zunahme der Polarität der Zinn-Chlor-Bindung mit steigender Zahl n hin. Die Phenyl-Zinn-Bindung erweist sich weniger polar als erwartet.

    Notes: Die PMR-Spektren der Organozinn-diäthylamide R4-nSn(N(C6H5)2]n (R=C2H5, C4H9) und der daraus durch Alkoholyse dargestellten Alkoxide R4-nSn(OR)n (R=CH3, C2H5, C4H9, C6H5; R′=CH3, C2H5) werden mitgeteilt und diskutiert. In Übereinstimmung mit unseren früheren Untersuchungen sprechen die Befunde bei den Organozinn-diäthylamiden für einen covalenten Bindungstyp, während die Spektren der Alkoxide mehr auf einen ionogenen Bindungscharakter schließen lassen. Die 1R-Spektren einiger Organozinn-alkoxide werden erläutert, eine Pentakoordination des Zinns in dessen Alkoxy-Verbindungen wird diskutiert.

    Notes: The reaction of niobocene trihydride [Cp2NbH3] with one equivalent of an alkyl- or aryltin halide XnSnR4-n (n = 1, 2) leads to products of the displacement of hydride by tin, i.e. [Cp2NbH2(SnX3-nRn)] [R = Me, n = 3 (1); R = Me, × = Cl, n = 2 (3); R = Ph, n = 3 (4); R = Ph, × = Cl, n = 2 (5); R = Et, × = Br, n = 2 (6)]. Use of an excess of the tin reagent results in a halodealkylation exchange reaction at the tin atom bound to the metal center. Reaction of the mono(silyl) complexes [Cp2NbH2(SiXMe2)] (X = Cl, Ph) with organotin halides XnSnR4-n gives products of the displacement of silicon by tin, whereas the bis(silyl) complex [Cp2NbH(SiPhMe2)2] does not undergo this reaction. The bis(tin)-substituted niobocene [Cp2NbH(SnMe3)2] has been prepared by the reaction of [Cp2NbH2(SnMe3)] with the tin amide Me3SnNMe2 under thermal conditions, as well as by the literature method of thermolysis of [Cp2NbH(η2-C2H3Ph)] in the presence of Me3SnH. Reaction of [Cp2NbH(SnMe3)2] with two equivalents of Cl2SnMe2 affords the bis(tin)-substituted complex [Cp2NbH(SnClMe2)2] (9). The possible presence of non-classical hypervalent H···Sn-Cl interactions in this compound has been assessed by means of X-ray structure analysis. The structural data for 9 are in accord with an essentially classical description as a tin-substituted dihydride complex without significant Sn···H interactions.
