GATTERMANN REACTION PDF

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.
