The Rosenmund reduction is a chemical reaction that reduces an acid halide to an aldehyde using hydrogen gas over palladium-on-carbon poisoned with barium sulfate. The reaction was named after Karl Wilhelm Rosenmund.
The catalyst must be poisoned because otherwise the catalyst is too active and will reduce the acid chloride to a primary alcohol.
Diisobutylaluminium hydride (DIBALH) can also reduce acid chlorides to aldehydes.
