Japanese: シアノエチル化 - シアノエチルカ
Cyanoethylation - Cyanoethyl Ca
A reaction to introduce the cyanoethyl group CNCH 2 CH 2 -. Organic compounds with active hydrogen (amines, alcohols, thiols, ketones, aldehydes, enamines, etc.) react with acrylonitrile in the presence of a base (caustic potassium KOH, amines) or a Lewis acid (AlCl 3 ), replacing the active hydrogen with a cyanoethyl group (equation (1)).
