Abstract
Addition of NHC -> SiCl4 to the highly Lewis acidic bis(pentafluoroethyl) silane ((C2F5)(2)SiH2) afforded the salt [(NHC)(2)SiCl2H][(C2F5)(2)SiCl3] with pentacoordinate silicon in the cation and the anion. The anion represents the first example of a chlorosilicate structurally characterized in the solid state. In this reaction, the long sought pentacoordinate NHC-adduct of silicochloroform was identified as an intermediate and its crystal structure is presented.
