  we present the synthesis and the detailed electron paramagnetic resonance (EPR) spectroscopic characterization of novel trivalent lead- and tin-based radicals comprising sterically demanding germyl substituents. The investigated radicals are derived from the recently reported trihypersilyl-substituted tetryl radicals ˙PbHyp3 and ˙SnHyp3. The tetryl radicals ˙Pb(Ge(SiMe3)3)3 (8), ˙Pb(Ge(SiMe3)3)2Si(SiMe3)3

• Dihypersilylstannylene and dihypersilylplumbylene—two Lewis-amphoteric carbene homologues
  作者：K Klinkhammer

  DOI：10.1016/s0277-5387(01)01029-4

  日期：2002.3

  Dihypersilylstannylene [(Me3Si)(2)Si](2)Sn (1) and dihypersilylplumbylene [(Me3Si)(3)Si](2)Pb (2) are Lewis-amphoteric compounds, i.e. they may behave as Lewis-acid and/or as Lewis-base. Quantum-chemical calculations indicate that their Lewis-acidity is strongly enhanced compared with their diorganyl substituted relatives by the electropositive silyl substituents present. Furthermore silyl substituents are expected to migrate more easily than organyl groups, due to relatively weak E-Si bonds formed to the heavier Group 14 congeners (tetrels) leading to different reaction patterns. Here I will give a brief report about our recent investigations on the chemical behavior of the title compounds towards other Lewis-acidic or Lewis-basic or Lewis-amphoteric species.
