How do you convert aniline to benzaldehyde?

How to convert aniline to benzaldehyde in one step – Quora. Take aniline with nitrous acid at 273–278K which yeilds Benzenediazonium salt. Now take Benzenediazonium salt with hypophosphorus acid which will yield benzene ring. Now by Gatterman koch synthesis we can get Benzaldehyde directly.

How do you convert aniline to aldehyde?

When one hydrogen atom on the benzene ring is replaced by the amine group, aniline is formed. Aniline undergoes substitution reactions. When aniline is treated with sodium nitride and hydrochloric acid it gives benzene diazonium chloride. The reaction occurs in cold conditions.

How do you convert aniline to benzene?

When aniline is treating with nitrating mixture or sodium nitrate in presence of a mineral acid like HCl, it results into benzene diazonium salt. This benzene diazonium salt is made to react with phosphinic acid to undergo reduction in presence of a metal like Cu or Zn to enhance the speed of the reaction.

What happens when aniline reacts with benzaldehyde?

The reaction of benzaldehyde with aniline produces benzalaniline which is a condensation reaction.

How do you make aniline benzoic acid?

This reaction involves three steps :

1. Step 1 : Conversion of aniline to benzene diazonium salt. When aniline react with in presence of hydrochloric acid to give benzene diazonium salt as a product.
2. Step 2 : Conversion of benzene diazonium salt to cyanobenzene.
3. Step 3 : Conversion of cyanobenzene to benzoic acid.

How phenol is converted into aniline?

Explanation:

1. To convert phenol ( ) into aniline ( ), it must be heated with ammonia in the presence of catalysts.
2. The catalyst used in this reaction is zinc chloride.
3. When phenol is heated with ammonia in the presence of zinc chloride as the catalyst at 473K, it loses the the hydroxyl group present in it.

How will you convert aniline?

Conversion of aniline to benzene diazonium chloride. When aniline is mixed with dilute hydrochloric acid (HCl) and an aqueous solution of sodium nitrate (NaNO2) at a temperature 273−278K , benzene diazonium chloride is formed. This reaction is called diazotization reaction.

How do you convert aniline?

The conversion of aniline to chlorobenzene actually consists of 2 steps. The first step is the reaction of aniline with $NaN{{O}_{2}}/HCl\text{ }$. This results in the formation of a diazonium salt, benzene diazonium chloride. This reaction occurs in the temperature range of $0-{{5}^{O}}C$ .

How will you convert aniline into 4 nitroaniline?

In the presence of pyridine, first treat aniline with (CH3CO2)2O. The product will be replaced by COCH3 with one H of -NH2. Use the Nitrating mix to treat this.

What happens when aniline reacts with acetaldehyde?

– Aniline reacts with acetaldehyde to form Schiff’s base.
