Preparation of Nitriles Nitriles can be prepared by substitution reactions of alkyl halides with cyanide salts: These are nucleophilic substitution reactions and we introduce the nitrile group by using the nucleophilicity of the cyanide ion. In a similar … Read more
Alkynes and nitriles are structurally similar, so let’s discuss how we can replace one of the carbons in the alkyne with a nitrogen: When one of the carbons is replaced, the carbon chain will be shortened by one. … Read more
There are a few ways of converting nitriles to amides. One of them is the sure way as it imposes no risk of your instructor counting it as invalid and taking some or all your points off. This is the … Read more
In this conversion series, we mention how nitriles can be converted to ketones and aldehydes. Nitriles are converted to ketones by both Grignard and organolithium reagents: The new C-C bonds are formed by nucleophilic addition of the organometallic … Read more
In the IUPAC nomenclature, nitriles can be named by systematic and common nomenclature. Systematic Nomenclature of Nitriles In the systematic nomenclature, the suffix “nitrile” is simply added to the name of the parent alkane that contains the CN group. … Read more
Both Grignard and organolithium reagents can be used to convert nitriles to ketones. The new C-C bonds are formed by nucleophilic addition of the organometallic reagents to the polar C-N triple bond. After protonation of the resulting anion, … Read more
Nitriles can be reduced to primary amines when treated with LiAlH4 or to aldehydes when a milder reducing agent such as DIBAL is used. Just like any other reduction reaction, an acidic or aqueous workup is needed to … Read more
Nitriles can be hydrolyzed to carboxylic acids in acidic aqueous solutions, and to carboxylate salts with base-catalyzed hydrolysis: In both cases, the transformation consists of two main parts: conversion of the nitrile to an amide and hydrolysis of … Read more
Preparation of Amides Amides can be prepared from acyl chlorides, esters, and carboxylic acids. The most straightforward should be the reaction with acid chlorides since they are the most reactive carboxylic acid derivatives, and amines are good nucleophiles too: … Read more
