| Application: | 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-trifluoroacetopheno |
| Application: | 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. |
