What does Dess Martin periodinane do?
Dess–Martin Periodinane (DMP) is among the most widely used reagents for the mild oxidation of alcohols to aldehydes and ketones. The neutral conditions of the oxidation reaction make it a suitable choice in syntheses of sensitive, functionally complex intermediates.
Is Dess Martin Periodinane toxic?
The Dess–Martin oxidation may be preferable to other oxidation reactions as it is very mild, avoids the use of toxic chromium reagents, does not require large excess or co-oxidants, and for its ease of work up….

How do you quench Dess Martin Periodinane?
Just do a simple filtration to remove it. If you use excess DMP, add few ml of water. It will hydrolyse DMP to insoluble IBX. Filter the precipitated IBA and IBX, using any common organic solvents, depending on the solubility of your product (DCM, chloroform, acetone, EtOAc, no alcohol).
Can DMP oxidize aldehydes?
Alcohols can be oxidized to aldehydes, ketones, and carboxylic acids depending on their structure and the type of oxidizing agent. In general, we can classify oxidizing agents as strong and mild.
What does Dess-Martin do to an alcohol?
Dess–Martin periodinane (DMP) is a chemical reagent used in the Dess–Martin oxidation, oxidizing primary alcohols to aldehydes and secondary alcohols to ketones.
Is DMP a strong oxidant?
Let’s call these “weak” oxidants. Examples of this are pyridinium chlorochromate (PCC), (DMP), the Swern oxidation [(COCl)2, DMSO, NEt3)] and CrO3/pyridine (the “ “) all shown below.
What is PCC oxidation?
Pyridinium chlorochromate (PCC) is a milder version of chromic acid. PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. In contrast to chromic acid, PCC will not oxidize aldehydes to carboxylic acids.

What is tempo oxidation?
In aqueous media, TEMPO is oxidized by the stoichiometric oxidant (sodium hypochlorite) to generate a nitrosonium cation, which is the actual oxidant of the alcohol. During the oxidation of the alcohol, the cation is reduced to a hydroxylamine.
What does DMP do Orgo?
The Dess-Martin Periodinane (DMP), a hypervalent iodine compound, offers selective and very mild oxidation of alcohols to aldehydes or ketones. The oxidation is performed in dichloromethane or chloroform at room temperature, and is usually complete within 0.5 – 2 hours.
Is Jones reagent strong?
– Jones reagent is one of the strong reagents which is used for the oxidation of primary alcohols to the carboxylic acid and secondary alcohols to the ketones.
Is Jones reagent strong oxidising agent?
But this says that it is an extremely strong oxidising agent and can oxidise Aldehydes to Carboxylic Acids too (thus giving acids on the oxidation of 1∘ alcohols).
Is the Dess-Martin periodinane ( DMP ) commercially available?
The Dess-Martin periodinane (DMP) is commercially available and decomposes only slowly.
What kind of oxidation does Dess-Martin periodinane do?
The Dess-Martin Periodinane (DMP), a hypervalent iodine compound, offers selective and very mild oxidation of alcohols to aldehydes or ketones.
Is it possible to neutralize Dess Martin periodinane?
It is possible to perform an oxidation with Dess-Martin periodinane under almost neutral conditions by adding pyridine to the reaction flask in order to neutralize the acetic acid, which is generated during the oxidation, and performing the work-up by treatment with sodium thiosulfate in the presence of a sodium bicarbonate buffer.2
How many EQs are in Dess Martin periodinane?
A ca. 0.05-0.35 M solution of the alcohola in dryb CH2Cl2,c containing 1 to 5 equivalents—typically 1.5 eq.—of Dess-Martin periodinaned (MW = 424.14; WARNING: this oxidant can explode) is stirrede at room tem-peraturef till most of the starting compound is consumed.
