General description

Trimethylsilyl cyanide participates in carbonyl aminomethylation via α-silyloxy nitriles.

Application

Trimethylsilyl cyanide was used:
  • for derivatization of complex metabolite mixtures by GC-MS
  • as cyanide source in enantioselective organocatalytic Strecker-type reaction of aliphatic N,N-dialkylhydrazones
  • as reagent for the cyanosilylation of aldehydes in near quantitative yield via catalysis by silylene-bridged rare earth oxide complexes
  • in asymmetric cyanosilylation with chiral dinuclear Ti(IV) complexes

Packaging

Packaging material contains granular sodium carbonate as a desiccant.

Reproducible and quantitative gas chromatography-mass spectrometry (GC-MS)-based metabolomics analysis of complex biological mixtures requires robust and broad-spectrum derivatization. We have evaluated derivatization of complex metabolite mixtures using trimethylsilyl cyanide (TMSCN) and the most commonly used silylation reagent N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA).

The enantioselective organocatalytic Strecker-type reaction of aliphatic N,N-dialkylhydrazones is presented. Using trimethylsilyl cyanide (TMSCN) as the cyanide source, the reaction can be efficiently catalyzed by a tert-leucine-derived bifunctional thiourea to afford the corresponding hydrazino nitriles in good to excellent yields
