Dihydrogen activation by a silylium silylene frustrated lewis pair and the unexpected isomerization reaction of a protonated silylene

The isolable silylene 1 forms a frustrated Lewis pair with silylium ion 2 that is able to split hydrogen under ambient conditions. The protonated silylene 3 obtained in this reaction isomerizes to yield the hydrogen-bridged disilyl cation 4. Cation 4 is fully characterized by NMR spectroscopy and by XRD analysis. Its formation via the protonated silylene 3 is indicated by independent synthesis of cation 3 by hydride abstraction from the corresponding dihydridosilane 11 and is further supported by the results of density functional calculations. Low coordinated silicon: The frustrated Lewis pair (FLP) formed from an isolable silylene and silylium ion activates dihydrogen (see scheme). In an unexpected follow-up reaction the silyl cation with a Si-H-Si linkage is formed.

Quantitative Assessment of the Lewis Acidity of Silylium Ions

The Lewis acidity of several aryl-substituted tetrylium ions was classified experimentally by applying the Gutmann-Beckett method and computationally by calculation of fluoride ion affinities (FIA) (tetrel elements = Si, Ge). According to these measures,

A new synthesis of triarylsilylium ions and their application in dihydrogen activation

Well-shuffled: An unexpected substituent distribution reaction via alkyldiarylsilylium ions leads to a distribution of substituents. Starting from alkyldiaryl silanes, this reaction provides a facile synthetic approach to sterically highly hindered triarylsilylium ions. These silylium ions can be applied in dihydrogen activation reactions. Copyright
