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.
