Rosenmund studied chemistry and received his Ph.D. 1906 from University of Berlin for his work with Otto Paul Hermann Diels. He discovered the Rosenmund reduction
, which is the reduction of acyl chloride
s to aldehydes over palladium-on-carbon catalyst. The Rosenmund-von Braun reaction, the conversion of an aryl bromide to an arylnitrile is also named after him.

Acyl chloride
In organic chemistry, an acyl chloride is an organic compound with the functional group -CO-Cl. Their formula is usually written RCOCl, where R is a side chain. They are usually considered to be reactive derivatives of carboxylic acids. A specific example of an acyl chloride is acetyl chloride,...
