Learn what is the gattermann reaction, who discovered it, its reaction mechanism, how it is different from the gattermann koch reaction with the help of examples. Gattermann reaction definition is – a synthesis of an aldehyde from an aromatic or heterocyclic compound, hydrogen cyanide, hydrogen chloride, and a catalyst. The Gattermann reaction, (also known as the Gattermann aldehyde synthesis) is a chemical reaction in which aromatic compounds are formylated by hydrogen.

Electrophilic aromatic substitution is an organic reaction in which an atom that is attached to an aromatic gzttermann usually hydrogen is replaced by an electrophile. I have to agree, gaytermann looks like an autocorrect nightmare. Much more reactive will likely form the sculpture ester first, in catalyze. An added drop of ferric chloride will turn the solution an intense red when aldehyde is present. Pyridine is used as a precursor to agrochemicals and pharmaceuticals and is also an important solvent and reagent.
