Silylated Sulfuric Acid: Preparation of a Tris(trimethylsilyl)oxosulfonium [(Me₃ Si-O)₃ SO]⁺ Salt.

ABSTRACT: The chemistry of silylated sulfuric acid, O₂ S(OSiMe₃ )₂ (T₂ SO₄ , T=Me₃ Si; also known as bis(trimethylsilyl) sulfate), has been studied in detail with the aim of synthesizing the formal autosilylation products of silylated sulfuric acid, [T₃ SO₄ ]⁺ and [TSO₄ ]^- , in analogy to the known protonated species, [H₃ SO₄ ]⁺ and [HSO₄ ]^- . The synthesis of the [TSO₄ ]^- ion only succeeds when a base, such as OPMe₃ that forms a weakly coordinating cation upon silylation, is reacted with T₂ SO₄ , resulting in the formation of [Me₃ POT]⁺ [TSO₄
