Cyano to carboxylic acid mechanism

WebSynthesis There are several methods of synthesizing nitriles. A common one is the treatment of an alkyl halide with sodium or potassium cyanide (RBr + KCN → RCN). Another method is the dehydration of the corresponding amide with a dehydrating agent such as phosphorus pentoxide (RCONH 2 → RCN). WebIntroduction. Cyanohydrin reactions occurs when an aldehyde or ketone gets treated by a cyanide anion (such as HCN) or a nitrile forming a cyanohydrin product. This special reaction is a nucleophilic addition, where the nucleophilic CN-attacks the electrophilic carbonyl carbon on the ketone, following a protonation by HCN, thereby the cyanide …
