The trimethylsilylation of acetylene

Chemical Communications, 2002
The gas-phase reaction of Me3Si+ ions with acetylene is remarkably sensitive to the environment, leading to substitution products in radiolytic systems at atmospheric pressure and to rearranged adduct ions in the FT-ICR cell at 10−8 Torr, while seeming unproductive in an intermediate pressure range.

The Rearrangement of the trimethylsilyl group in (trimethylsilyl)pyrazoles

Journal of Organometallic Chemistry, 1971
Abstract A new class of compounds, the N-(trimethylsilyl)pyrazoles, has been prepared. Four compounds with differing substituents on the pyrazole ring show non-equivalent 3,5-substituents in their NMR spectra. These compounds undergo temperature-dependent NMR spectral changes with the 3,5-substituents becoming equivalent at high temperatures.

MASS SPECTROMETRIC FRAGMENTATION OF TRIMETHYLSILYL AND RELATED ALKYLSILYL DERIVATIVES.

Mass spectrometry reviews (Print), 2019
This review describes the mass spectral fragmentation of trimethylsilyl (TMS) and related alkylsilyl derivatives used for preparing samples for analysis, mainly by combined gas chromatography and mass spectrometry (GC/MS).

Salt-Free Reduction of Transition Metal Complexes by Bis(trimethylsilyl)cyclohexadiene, -dihydropyrazine, and -4,4'-bipyridinylidene Derivatives.

Accounts of Chemical Research, 2019
Chemical reduction of transition metals provides the corresponding low-valent transition metal species as a key step for generating catalytically active species in metal-assisted organic transformations and is a fundamental unit reaction for preparing ...
