How do you reduce amides to amines?
Find step-by-step Chemistry solutions and your answer to the following textbook question: What amides would you react with $$ LiAlH_4 $$ to form the following amines? a. benzylmethylamine, b. ethylamine, c. diethylamine, d. triethylamine.
How do primary and secondary amides react with hydride?
Treatment of amide with bromine in aqueous solution of sodium hydroxide. In Hoffmann Bromide degradation as the word, suggest, the amide is reduced to an amine with 1- carbon less, so this is the method in which we don't get the same number of carbon atom in product as it …

What is added to the carbon of nitrile?
In the first part of the mechanism, the first hydride is added to the electrophilic carbon of the nitrile. This form an intermediate that complexes with the AlH 3 which is also formed during the reaction. And in the second part of the mechanism, the second equivalent of hydride and the AlH 3 is added.
What is the treatment for nitriles?
Treatment of nitriles with a strong hydride reducing agents such as lithium aluminum hydride results in double hydride addition, giving primary amine on aqueous workup. The mechanism of the reaction involves the nucleophilic addition of hydride to the polarized carbon-nitrogen double bond. This reduction requires the addition of two equivalents of hydride from lithium aluminum hydride.
What is the purpose of an aqueous acidic solution?
An aqueous acidic solution is often used to carry out the protonolysis step that follows the L i A l H X 4 reduction (as shown in the following mechanism). The excess of acid that is typically used converts the amine, which is a base, into its conjugate-acid ammonium ion.
Does L I H X 4 reduce amides?
I know that L i A l H X 4 is able to reduce amides into amines, e.g. benzamide into benzylamine. However, I am unsure what other by-products are formed as a result.
