GATTERMANN REACTION

GATTERMANN REACTION

• The Gattermann reaction, (also known as the Gattermann aldehyde synthesis) is a chemical reaction in which aromatic compounds are formylated by hydrogen cyanide in the presence of a Friedel–Crafts catalyst (e.g. AlCl₃).
• This Reaction is same as SANDMEYER REACTION. But the only difference between both of them is that here we use COPPER POWDER (Cu) in the presence of HCl/HBr, and in SANDMEYER REACTION we use Cu₂Cl₂/Cu₂Br₂ as catalyst.
