The electroreduction of benzyl cyanide on iron and cobalt cathodes
- 161 Downloads
An electrochemical method for preparing amines from organic cyanides using iron black and cobalt black cathodes has been studied. Benzyl cyanide underwent smooth reduction at a cobalt black cathode in an aqueous ethanolic ammonium sulphate medium to give a 74% yield of 2-phenylethylamine with a current efficiency of 50%; whereas with an iron black cathode under the same conditions, a 57% yield of 2-phenylethylamine has been obtained with a current efficiency of 33%.
