Vedclass · Answer

(D) Let us analyze each reaction:$A$. Gattermann-Koch reaction: Benzene reacts with $CO + HCl$ in the presence of anhydrous $AlCl_3$ or $CuCl$ to give benzaldehyde. The reaction shown with $HCN + HCl$ (Gattermann reaction) also yields benzaldehyde.$B$. Etard reaction: Toluene reacts with chromyl chloride $(CrO_2Cl_2)$ followed by hydrolysis to give benzaldehyde.$C$. Toluene reacts with chromic oxide $(CrO_3)$ in acetic anhydride followed by hydrolysis to give benzaldehyde (this is a variation of the Etard reaction).$D$. Reimer-Tiemann reaction: Phenol reacts with chloroform $(CHCl_3)$ and aqueous $KOH$ to give salicylaldehyde (o-hydroxybenzaldehyde) as the major product,not benzaldehyde.Therefore,option $D$ does not yield benzaldehyde.

Which of the following reactions does not give benzaldehyde as a product?
