The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Trimethylphosphineoxide(SMILESS: CP(C)(C)=O,cas:676-96-0) is researched.Formula: C10H21NO4. The article 《Silylated Sulfuric Acid: Preparation of a Tris(trimethylsilyl)oxosulfonium [(Me3Si-O)3SO]+ Salt》 in relation to this compound, is published in Angewandte Chemie, International Edition. Let’s take a look at the latest research on this compound (cas:676-96-0).
The chem. of silylated sulfuric acid, O2S(OSiMe3)2 (T2SO4, T=Me3Si; also known as bis(trimethylsilyl) sulfate), has been studied in detail with the aim of synthesizing the formal autosilylation products of silylated sulfuric acid, [T3SO4]+ and [TSO4]-, in analogy to the known protonated species, [H3SO4]+ 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 T2SO4, resulting in the formation of [Me3POT]+[TSO4]-. [T3SO4]+ salts could be isolated starting from T2SO4 in the reaction with [T-H-T]+[B(C6F5)4]- or T+[CHB11Br6H5]- when a weakly coordinating anion is used as counterion. All silylated compounds could be crystallized and structurally characterized.
