Applications in organic chemistry
In organic synthesis, CAN is useful as an oxidant for many
functional groups (alcohols, phenols, and ethers) as well as C–H
bonds, especially those that are benzylic. Alkenes undergo
dinitroxylation, although the outcome is solvent-dependent.
Quinones are produced from catechols and hydroquinones and even
nitroalkanes are oxidized.
For the synthesis of heterocycles in Pharma industry
Catalytic amounts of aqueous CAN allow the efficient synthesis of
quinoxaline derivatives. Quinoxalines are known for their
applications as dyes, organic semiconductors, and DNA cleaving
agents. These derivatives are also components in antibiotics such
as echinomycin and actinomycin. The CAN-catalyzed three-component
reaction between anilines and alkyl vinyl ethers provides an
efficient entry into 2-methyl-1,2,3,4-tetrahydroquinolines and the
corresponding quinolines obtained by their aromatization.
As a deprotection reagent
CAN is traditionally used to release organic ligands from metal
carbonyls. In the process, the metal is oxidised, CO is evolved,
and the organic ligand is released for further manipulation.
CAN is used to convert para-methoxybenzyl and 3,4-dimethoxybenzyl
ethers, which are protecting groups for alcohols. Two equivalents
of CAN are required for each equivalent of para-methoxybenzyl
ether. The alcohol is released, and the para-methoxybenzyl ether
converts to para-methoxybenzaldehyde.
CAN is also a component of chrome etchant, a material that is used in the production of photomasks and liquid crystal displays. Cerium (IV) ammonium nitrate ((NH4)2Ce(NO3)6) is a one-electron
oxidizing agent that is used for oxidative addition reactions of
electrophilic radicals to alkenes, enabling intermolecular and
intramolecular carbon-carbon and carbon-heteroatom bond formation.
CAN also oxidizes secondary alcohols into ketones and benzylic
alcohols into aldehydes. Cerium Ammonium Nitrate used for chemical reagent and ternary catalyst. It is a specialised oxidizing agent in organic synthesis and a
standard oxidant in quantitative analysis.
