Rosenmund reaction: Learn how to make aldehydes from

Learn how to make aldehydes from acyl chlorides using palladium and barium sulfate in the Rosenmund reaction . Find out the mechanism, applications, and limitations of this hydrogenation process. A hydrogenation process that selectively reduces acyl chlorides to aldehydes with palladium catalyst. Learn about the reaction history, mechanism, catalyst preparation, and related methods. Rosenmund reduction reaction is a hydrogenation mechanism that reduces an acyl chloride to an aldehyde preferentially. The reaction is named after Karl Wilhelm Rosenmund , who found the reactions in 1918. The Rosenmund reduction involves the catalytic hydrogenation of acyl chlorides (RCOCl) to aldehydes (RCHO) using hydrogen gas in the presence of a palladium-based catalyst. Alfa Chemistry introduces the overview, reaction mechanism, and application cases of Rosenmund reduction.
