설명

애플리케이션

Ethyl cyanoformate can be used as a cyanide source for the cyanation of:

• Activated olefins in the presence of a titanium catalyst.
• Carbonyl compounds catalyzed by 4-dimethylaminopyridine (DMAP) to yield corresponding cyanohydrin carbonates under metal-free and solvent-free conditions.
• Aldehydes and 2,2,2-trifluoroacetophenone catalyzed by N-heterocyclic carbene (NHC) to yield corresponding cyanohydrins ethyl carbonates.

Ethyl cyanoformate is a general cyanating agent. It can be used in the nucleophilic addition of cyanide to carbonyl compounds, oxidative cyanation of tertiary amines and in the synthesis of β-cyano-substituted acrylates from alkynes.
