Beschreibung

N,N'-Dicyclohexylcarbodiimide is a carboxyl activating reagent used in peptide synthesis. It acts as a dehydrating agent for the preparation of amides, ketones and nitriles. It is involved in the preparation of esters by reacting tertiary alcohols with carboxylic acid. It is utilized for the stereo chemical inversion of secondary alcohols by forming formyl ester followed by saponification. It is associated with dimethyl sulfoxide and used in Pfitzner-Moffatt oxidation to convert alcohols into aldehydes and ketones.

Anwendungen
N,N′-Dicyclohexylcarbodiimid ist ein carboxylaktivierendes Reagenz, das in der Peptidsynthese eingesetzt wird. Es dient als Trocknungsmittel für die Zubereitung von Amiden, Ketonen und Nitrilen. Es ist an der Herstellung von Estern beteiligt, indem es tertiäre Alkohole mit Carbonsäure reagieren lässt. Es wird für die stereochemische Inversion von sekundären Alkoholen unter Bildung von Formylester und anschließender Verseifung verwendet. Es ist mit Dimethylsulfoxid verbunden und wird bei der Pfitzner-Moffatt-Oxidation zur Umwandlung von Alkoholen in Aldehyde und Ketone verwendet.

Löslichkeit
Löslich in Methanol, Chloroform, Dichlormethan, Acetonitril, Tetrahydrofuran und Dimethylformamid. Unlöslich in Wasser.
