Description and Uses
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.
