The hydrolysis of nitriles. Introduction. When nitriles are hydrolysed you can think of them reacting with water in two stages - first to produce an amide, and then the ammonium salt of a carboxylic acid. For example, ethanenitrile would end up as ammonium ethanoate going via ethanamide. In practice, the reaction between
You will find a link to a separate page about the mechanisms for the reaction. Replacing a halogen by -CN. Reactions. If a halogenoalkane is heated under reflux with a solution of sodium or potassium cyanide in ethanol, the halogen is replaced by a -CN group and a nitrile is produced. Heating under reflux means heating
Background on the nitriles, including their physical properties. What are nitriles? Nitriles contain the -CN group, and used to be known as cyanides. Some simple nitriles. The smallest organic nitrile is ethanenitrile, CH3CN, (old name: Note: Compounds like this are formed when aldehydes react with hydrogen cyanide.
Facts and mechanisms for the reactions between halogenoalkanes and cyanide ions - nucleophilic substitution. If a halogenoalkane is heated under reflux with a solution of sodium or potassium cyanide in ethanol, the halogen is replaced by a -CN group and a nitrile is produced. Heating under reflux means heating with

A summary of the ways of making nitriles from halogenoalkanes, amides, and aldehydes and ketones. the ionic one, but it slightly obscures what's going on: The bromine (or other halogen) in the halogenoalkane is simply replaced by a -CN group - hence a substitution reaction. In this example, butanenitrile is formed.

A summary of the ways of making nitriles from halogenoalkanes, amides, and This reaction is discussed on the page about the reactions between halogenoalkanes and hydroxide ions. Use the To the
The simple nucleophilic addition reactions of aldehydes and ketones with hydrogen cyanide and with sodium hydrogensulphite (bisulphite) used to be known as cyanohydrins. For example, with ethanal (an aldehyde) you get 2-hydroxypropanenitrile: With propanone (a ketone) you get 2-hydroxy-2-methylpropanenitrile:
This page looks at the reduction of nitriles to primary amines using either lithium tetrahydridoaluminate(III) (lithium aluminium hydride) or hydrogen and a The nitrile reacts with the lithium tetrahydridoaluminate in solution in ethoxyethane (diethyl ether, or just "ether") followed by treatment of the product of that reaction with
