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.

Please tell us where you read or heard it including the quote, if possible. It is named for the German chemist Ludwig Gattermann [1] and is similar to the Friedel—Crafts reaction. Li, Jie Jack Member feedback about Scientific phenomena named after people: The first Lewis acid-catalyzed Diels—Alder reaction In Lewis acid catalysis of organic reactions, a metal-based Lewis acid acts as an electron pair acceptor to increase the reactivity of a substrate. Formylation has been identified in several critical biological processes.

In clinical chemistry it has been suggested as a proliferation marker for prognosis, verification of diagnosis, control of treatment particularly as a companion diagnostic and follow-up of malignant disease.

Member feedback about Psoralen: An example of the Zn CN 2 method is the synthesis of mesitaldehyde from mesitylene. The compound is often cited as a Lewis acid.
