Chapter 21: Q36P-a (page 1129)

Show how you would accomplish the following synthetic transformations. You may use any necessary reagents.(a)N-ethylbenzamide→benzylethylamine

Short Answer

Expert verified

Synthetic transformation for N-ethylbenzamide to benzylethylamine is show as,

Step by step solution

01

Step-by-Step SolutionStep 1: Use of  LiAIH4reagent

LiAIH4is a strong reducing agent for polar double bonds, as it easily thought of as a source of H− . It will reduce aldehydes, ketones,esters, carboxylic acid chloride, carboxylic acids and even carboxylate salts to alcohols.


LiAIH4is also reduce the amide and nitriles to amine, In above reaction amide is reduce to amine.

02

Synthesis of benzylethylamine from N-ethylbenzamide

When N-ethylbenzamide react withLiAIH4andH2Othen there is a formation of benzylethylamine, in this reaction carbonyl group are direct reduce to alkane.

Formation of benzylethylamine

Explain this curious result. What does this reaction tell you about the relative reactivity of esters and ketones?

Complete the mechanism for this acid-catalyzed transesterification by drawing out all the individual steps. Draw the important resonance contributors for each resonance stabilized intermediate.

An ether extraction of nutmeg gives large quantities of triolein, a waxy crystalline solid of melting point 57 °C. The IR spectrum of triolein shows a very strong absorption at1735 cm-1 . Basic hydrolysis of triolein gives 1 equivalent of glycerol and 3 equivalents of oleic acid ((9Z)-Octadec-9-enoic acid).

(a) Draw the structure of triolein.

(b) Predict the products formed when triolein is treated with lithium aluminum hydride, followed by aqueous hydrolysis of the aluminum salts.

What characteristics of the phenyl propanoate spectrum rule out an aldehyde or carboxylic acid functional group giving the absorption at 1730 cm-1?
