  Dihypersilylstannylene and dihypersilylplumbylene—two Lewis-amphoteric carbene homologues

  摘要：

  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.
