The given multistep synthesis by using necessary reagents is to be shown. Concept introduction: In the synthesis of para-butyl aniline the starting material is benzene. This on acid hydrolysis converts to ketonic product. Ketonic product reduces to butyl benzene which on nitration in presence of nitric acid and sulphuric acid gives a mixture of ortho-para products. After the separation of para product it further reduces in the presence of metallic catalyst to the butyl aniline.

Question

Synthesize the products shown below starting from the reactants provided and using any other necessary reagents. Clearly draw out all reagents and intermediates on the pathway to the product.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone

Concept introduction:

In the given synthesis the starting material is biphenyl compound. In the compound of biphenyl two benzene rings are attached with each other by the carbon-carbon bond and with the loss of two hydrogen atoms. Biphenyl first undergoes nitration with nitric acid and sulphuric acid. Then it undergoes reduction for nitro group to amine group. Biphenyl amine reacts with ethyl chloride and converts to ethylbiphenyl amine. On further reduction and reaction with suitable reagent desired product is formed.
