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 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]
Gordon’s functional health patterns is a method devised by Marjory Gordon to be used by nurses in the nursing process to provide a more comprehensive nursing assessment of the patient.
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.
Aldehyde dehydrogenase is a polymorphic enzyme [3] responsible for the oxidation of aldehydes to carboxylic acids. [3] There are three different classes of these enzymes in mammals: class 1 (low K m, cytosolic), class 2 (low K m, mitochondrial), and class 3 (high K m, such as those expressed in tumors, stomach, and cornea).
The Wolff–Kishner reduction is a reaction used in organic chemistry to convert carbonyl functionalities into methylene groups. [1] [2] In the context of complex molecule synthesis, it is most frequently employed to remove a carbonyl group after it has served its synthetic purpose of activating an intermediate in a preceding step.
Aldehydes and ketones can be reduced respectively to primary and secondary alcohols. In deoxygenation, the alcohol group can be further reduced and removed altogether by replacement with H. Two broad strategies exist for carbonyl reduction. One method, which is favored in industry, uses hydrogen as the reductant.
The Dakin oxidation. The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide (H 2 O 2) in base to form a benzenediol and a carboxylate.
