The Mozingo reduction, also known as Mozingo reaction or thioketal reduction, is a chemical reaction capable of fully reducing a ketone or aldehyde to the corresponding alkane via a dithioacetal. [1] [2] The reaction scheme is as follows: [3]
Some examples of functionality reduced by SmI 2 are provided below. The reactivity of SmI 2 is significantly affected by the choice of solvent. The use of hexamethylphosphoramide (HMPA) as a co-solvent in samarium(II) iodide reductions allows the reaction to be carried out under much milder conditions than in its absence. [ 6 ]
In organic chemistry, the Myers deoxygenation reaction is an organic redox reaction that reduces an alcohol into an alkyl position by way of an arenesulfonyl hydrazine as a key intermediate. This name reaction is one of four discovered by Andrew Myers that are named after him; this reaction and the Myers allene synthesis reaction involve the ...
In its use as a qualitative test for aldehydes, the unknown sample is added to the decolorized Schiff reagent; when aldehyde is present a characteristic magenta color develops. Schiff-type reagents are used for various biological tissue staining methods, e.g. Feulgen stain and periodic acid-Schiff stain.
Deoxygenation is a chemical reaction involving the removal of oxygen atoms from a molecule. The term also refers to the removal of molecular oxygen (O 2 ) from gases and solvents, a step in air-free technique and gas purifiers .
The second step is the deoxygenation of the pinacolate, which yields the alkene, this second step exploits the oxophilicity of titanium. A proposed mechanism when TiCl 4 and Zn(Cu) are used for the coupling of benzophenone, as proposed in a reference. [3] Note that the mechanism may vary when different conditions are used.
An acyl-diazomethane can react with an aldehyde to form a β-diketone in the presence of a transition metal catalyst (SnCl 2 in the example shown below). β-Diketones are common biological products, and as such, their synthesis is relevant to biochemical research.
The reaction of periodic acid oxidizes vicinal diols in these sugars, usually breaking up the bond between two adjacent carbons not involved in the glycosidic linkage or ring closure in the ring of monosaccharide units that are part of the long polysaccharides and creating a pair of aldehydes at the two free tips of each broken monosaccharide ...
