The Rosenmund reaction is a hydrogenation process where molecular hydrogen reacts with acyl chloride in the presence of palladium or barium sulfate catalyst. Barium sulfate reduces the activity of palladium due to its low surface area, thereby preventing over reduction.

Catalyst used in Rosenmund reduction is
1 \(Pd /\) \(BaS{O_4}\)
2 \(Zn-Hg\) \(couple\)
3 \(LiAl{H_4}\)
4 \(Ni/{H_2}\)
