Vedclass · Answer

(C) The Gatterman-Koch reaction is a specific form of Friedel-Crafts acylation used to introduce a formyl group $(-CHO)$ into an aromatic ring. In this reaction,benzene is treated with carbon monoxide $(CO)$ and hydrogen chloride $(HCl)$ in the presence of anhydrous aluminum chloride $(AlCl_3)$ or cuprous chloride $(CuCl)$ to produce benzaldehyde. The reaction is represented as: $C_6H_6 + CO + HCl \xrightarrow{anhydrous \ AlCl_3 / CuCl} C_6H_5CHO$.

Which reagent is used in the preparation of benzaldehyde from benzene by the Gatterman-Koch reaction?
