Anwendungen

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.

Bemerkungen

Incompatible with strong oxidizing agents.
