General description

N,N′-Diisopropylcarbodiimide (DIC) is a carbodiimide used as a coupling reagent in the synthesis of amides, peptides, ureas, heterocycles, and unsymmetrical carbodiimides. It is also used in the polymerization reactions as an activator.

Application

N,N′-Diisopropylcarbodiimide can be used:
  • To synthesize lanthanide (Ln) guanidinate complexes via insertion of carbodiimide into the Ln-N bond of lanthanocene secondary amido complexes.
  • To facilitate the cyclization of N-(β-Hydroxy)amides to form 2-oxazolines.
  • To synthesize 1-isopropyl-2-alkoxycarbonyl-3-isopropyliminio-aziridine by reacting with alkyl diazoacetates in the presence of transition metal salts.

DIC can be used as:
  • A coupling reagent for the synthesis of various esters and amides by treating carboxylic acids with phenols and amines respectively.
  • A reagent for the conversion of alcohols to aldehydes or ketones in the presence of DMSO via modified Moffatt-type oxidation reaction.
  • A reagent to facilitates the preparation of alkyl halides from corresponding alcohols via the formation of o-alkylisourea.

Alternative to dicyclohexylcarbodiimide in peptide synthesis.
