On Silylated Oxonium and Sulfonium Ions and Their Interaction with Weakly Coordinating Borate Anions.

ABSTRACT: Attempts have been made to prepare salts with the labile tris(trimethylsilyl)chalconium ions, [(Me₃ Si)₃ E]⁺ (E=O, S), by reacting [Me₃ Si-H-SiMe₃ ][B(C₆ F₅ )₄ ] and Me₃ Si[CB] (CB^- =carborate=[CHB₁₁ H₅ Cl₆ ]^- , [CHB₁₁ Cl₁₁ ]^- ) with Me₃ Si-E-SiMe₃ . In the reaction of Me₃ Si-O-SiMe₃ with [Me₃ Si-H-SiMe₃ ][B(C₆ F₅ )₄ ], a ligand exchange was observed in the [Me₃ Si-H-SiMe₃ ]⁺ cation leading to the surprising formation of the persilylated [(Me₃ Si)₂ (Me
