ISBN 0-8493-3623-6.In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.

The alcohol is released, and the para-methoxybenzyl ether converts to para-methoxybenzaldehyde. Two equivalents of CAN are required for each equivalent of para-methoxybenzyl ether. For example, with the Wulff–Dötz reaction an alkyne, carbon monoxide, and a chromium carbene are combined to form a chromium half-sandwich complex and the phenol ligand can be isolated by mild CAN oxidation.ĬAN is used to cleave para-methoxybenzyl and 3,4-dimethoxybenzyl ethers, which are protecting groups for alcohols. In the process, the metal is oxidised, CO is evolved, and the organic ligand is released for further manipulation. 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.ĬAN is traditionally used to release organic ligands from metal carbonyls. These derivatives are also components in antibiotics such as echinomycin and actinomycin. Quinoxalines are known for their applications as dyes, organic semiconductors, and DNA cleaving agents. Oxidative halogenation can be promoted by CAN as an in situ oxidant for benzylic bromination, and the iodination of ketones and uracil derivatives.įor the synthesis of heterocycles Ĭatalytic amounts of aqueous CAN allow the efficient synthesis of quinoxaline derivatives. ĬAN provides an alternative to the Nef reaction for example, for ketomacrolide synthesis where complicating side reactions usually encountered using other reagents. Quinones are produced from catechols and hydroquinones and even nitroalkanes are oxidized. Alkenes undergo dinitroxylation, although the outcome is solvent-dependent. 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. In the redox process Ce(IV) is converted to Ce(III), a one-electron change, signaled by the fading of the solution color from orange to a pale yellow (providing that the substrate and product are not strongly colored).Īpplications in organic chemistry Few shelf-stable reagents are stronger oxidants. N.H.E.) it is an even stronger oxidizing agent than Cl 2 ( E° ≈ 1.36 V). In terms of its redox potential ( E° ≈ 1.61 V vs. Ĭe 4+ is a strong one-electron oxidizing agent. The anion 2− has T h (idealized O h) molecular symmetry.
