Abstract:The compound 2-cyanoethyl-5-norbornene-2-carboxaldehyde is a key intermediate of 2-chloro-5-chloromethylpyridine through cyclopentadiene- acraldehyde method. 2-cyanoethyl-5-norbornene-2- carboxaldehyde was synthesized through a Michael addition reaction of acrylonitrile and 5-norbornene-2- carboxaldehyde using tert-butyl alcohol and potassium hydroxide as catalyst at room temperature. The optimum reaction conditions were obtained via experiments with a yield of the title product of above 98%. |
Key words:2-cyanoethyl-5-norbornene-2-carboxaldehyde; Michael addition reaction; catalyst; retarder |
