화학적 성질
Clear Colourless Liquid용도
Ethyl cyanoformate is used as reagent in the preparation of N-substituted amindinoformic acid and ethyl-4-quinazoline -2-carboxylate.주요 응용
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.
Purification Methods
Dissolve the cyanoformate in Et2O, dry it over Na2SO4, filter, evaporate and distil it [Malachowsky et al. Chem Ber 70 1016 1937, Adickes et al. J Prakt Chem [2] 133 313 1932, Grundmann et al. Justus Liebigs Ann Chem 577 77 1952]. [Beilstein 2 IV 1862.]주의 사항
Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong acids, strong bases, strong oxidizing agents and strong reducing agents.시아노포름산에틸에스테르 준비 용품 및 원자재
