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.
