  Synthesis of the First Persilylated Ammonium Ion, [(Me₃Si)₃NSi(H)Me₂]⁺, by Silylium-Catalyzed Methyl/Hydrogen Exchange Reactions

  摘要：

  This work describes the unexpected synthesis and characterization of the first persilylated ammonium ion, [(Me3Si)(3)NSi(H)Me-2](+), in the reaction of (Me3Si)(3)N with [Me3Si-H-SiMe3][B(C6F5)(4)]. NMR and Raman studies revealed a transition-metal-free silylium ion catalyzed substituent redistribution process when [Me3Si-H-SiMe3](+) was used as the silylating reagent. These observations were affirmed in the reaction with [Et3Si-H-SiEt3][B(C6F5)(4)]. A Lewis acid catalyzed scrambling process always occurs if an excess of silanes is present in the formation of silylium cations while employing the standard Bartlett-Schneider-Condon type reaction. Additionally, the thermodynamics of this process was accessed by DFT computations at the pbelpbeiaug-cc-pVDZ level, indicating alkyl substituent exchange equilibria at the silane and preference of the formation of [(Me3Si3NSi(H)Me-2](+) over [(Me(3)Si(4)Nr](+).

  to the protonated species, phosphoric acid (H3PO4) reaction of OP(OSiMe3)3 with a base led to the formation of the unknown [O2P(OSiMe3)2]− anion, which could be crystallized as potassium salt and structurally characterized, too. Both [P(OSiMe3)4]+ and [O2P(OSiMe3)2]− can be regarded as the formal autoprotolysis products of OP(OSiMe3)3.

  (Me3Si)(2)CNN isomerizes upon addition of traces of [Me3Si](+) ions to give (Me3Si)(2)NNC, which then undergoes an unusual trimerization reaction to give exclusively 4-diazenyl-3-hydrazinylpyrazole. As catalyst the isonitrilium ion, [(Me3Si)(2)NNC-(SiMe3)](+), was identified and fully characterized. Experiments and computations indicate a three-step reaction including isomerization of diazomethane, a C-C or N-C coupling, and a formal cycloaddition reaction. The kinetics and thermodynamics are discussed on the basis of DFT calculations.
