Abstract: | The Sodium Silanide t Bu2PhSiNa: Synthesis, Properties, Structure Analysis – a Synthetic Pathway to Introduce the t Bu2PhSi‐Ligand The sodium silanide tBu2PhSiNa is easily obtained by the reaction of sodium metal with tBu2PhSiBr at elevated temperatures in n‐heptane, THF or dibutylether. An X‐ray crystal structure analysis reveals, that the sodium silanide 3 contains chains of tBu2PhSiNa units with η6 sodium–phenyl‐contacts. Oxidation of tBu2PhSiNa with TCNE proceeds with formation of the disilane tBu2PhSi–SiPhtBu2. |
