Question

Name the Reagent used for converting toluene to benzaldehyde

Answer 1

The most common way to convert toluene into benzaldehyde is through the Etard reaction. The reagent used is cro2cl2. Chromyl chloride `(CrO_(2)Cl_(2))` in `CS_(2)` or chromium trioxide `(CrO_(3))` in acetic anhydride.

What is Etard's reaction:

• Toluene and chromic oxide can also be used to oxidize toluene in acetic anhydride to produce benzaldehyde. Acetic anhydride and benzaldehyde combine to make benzylidene diacetate, which is then hydrolyzed by alkali or acid to produce benzaldehyde.

• By using chromyl chloride, toluene is transformed into benzaldehyde in an oxidation reaction. Etard's response is the name given to this process. Compounds with at least one methyl group linked to the benzene ring are necessary for this reaction. As a result of oxidation, the methyl group becomes an aldehyde group.

• The Sigmatropic Rearrangement, a pericyclic process, aids in the breakdown of the Etard complex. The product is purified using several solvents to prevent breakdown. The end result of this solution's purification is pure benzaldehyde, a high-quality product.
