  A new strategy for the synthesis of homologously pure linear polystannane oligomers

  摘要：

  The reagent 6 is utilized for the stepwise synthesis of linear polystannane oligomers in which hydrostannolysis is employed as the Sn-Sn bond-forming reaction, and DIBAL-H is used to regenerate a new Sn-H functionality for extended chain growth through repetition of the two-step reaction sequence. The electronic spectra of these oligomers are influenced by chain length and the specific placement of substituents, as demonstrated by the homologous series 7, 9, and 13-15 and the phenylated di- and tristannanes 18-20.

  The synthesis and full characterization, including detailed Sn-119 NMR analysis, of the new series of oligostannanes X-(Bu2Sn)-Sn-n-[(Bu2Sn)-Sn-n](m)-(Bu2Sn)-Sn-t-[(Bu2Sn)-Sn-n](n)-(SnBu2CH2CH2OEt)-C-n (1a, X = 2-ethoxyethyl, m = n = 0; 2a, X = Bu-n, m = 0, n = 1; 3a, X = 2-ethoxyethyl, m = n = 1; 4a, X = Bu-n, m = 1, n = 2; 5a, X = 2-ethoxyethyl, m = n = 2; 6a, X = 2-ethoxyethyl, m = n = 3) that incorporate a single (Bu2Sn)-Sn-t group are reported. Comparison of this new spectroscopic database, in particular, electronic spectra and Sn-119 NMR parameters, with those obtained for known analogous per-n-butylated derivatives, including the three compounds (EtOCH2CH2Bu2Sn)-Sn-n-[(Bu2Sn)-Sn-n](n)-(SnBu2CH2CH2OEt)-C-n (1c (n = 1), 2c (n = 2), and 3c (n = 3)), which are prepared for the first time in pure form, suggest that 1a-6a are free of structural distortions caused by steric interactions between substituents on adjacent tin atoms. Accordingly, dramatic perturbations that are observed in the (1)J(Sn-119-Sn-119) values for Sn-Sn bonds that incorporate the (Bu2Sn)-Sn-t group in these compounds, relative to the per-n-butyl derivatives, are proposed to arise from an electronic effect of the tert-butyl substituent.
