Rosenmund reduction is used for the preparation of Aldehydes. The catalyst used in this reaction is
Ans. The catalyst used in the Rosenmund reduction is Palladium on Barium sulfate (Pd/BaSO4Pd/BaSO4). This catalyst facilitates the reduction of acyl chlorides (acid chlorides) to aldehydes under mild conditions, often using hydrogen gas (H2H2) as the reducing agent. The Rosenmund reduction is a useful method for the synthesis of aldehydes.
