ARNDT EISTERT REACTION PDF

In organic chemistry , the Arndt—Eistert reaction is the conversion of a carboxylic acid to its homologue. Named for the German chemists Fritz Arndt — and Bernd Eistert — , the method entails treating an acid chlorides with diazomethane. Aside from the acid chloride substrate, three reagents are required: diazomethane, water, and a metal catalyst. Each has been well investigated.

Arndt-Eister reaction

The Arndt—Eistert synthesis is a series of chemical reactions designed to convert a carboxylic acid to a higher carboxylic acid homologue i. Acid chlorides react with diazomethane to give diazoketones. In the presence of a nucleophile water and a metal catalyst Ag 2 O , diazoketones will form the desired acid homologue. While the classic Arndt—Eistert synthesis uses thionyl chloride to convert the starting acid to an acid chloride, any procedure can be used that will generate an acid chloride. Diazoketones are typically generated as described here, but other methods such as diazo-group transfer can also apply. Since diazomethane is toxic and violently explosive, many safer alternatives have been developed, such as the usage of ynolates Kowalski ester homologation or diazo trimethylsilyl methane.
