Description

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.
