Ozonolysis of oleic acid is an important route to azelaic acid. The coproduct is nonanoic acid: [20] CH 3 (CH 2) 7 CH=CH(CH 2) 7 CO 2 H} + 4 O 3 → HO 2 C(CH 2) 7 CO 2 H} + CH 3 (CH 2) 7 CO 2 H. Erucic acid is a precursor to brassylic acid, a C13-dicarboxylic acid that is used to make specialty polyamides and polyesters.
R)-2-Methylpent-4-enoic acid can also be used in synthesis of other chiral compounds. For example, it has been used in the process of synthesizing the drug Sacubitril as a reagent for adding a chiral center to the molecule. [2]
Methylpentene is an alkene with a molecular formula C 6 H 12.The prefix "methyl-" is derived from the fact that there is a methyl(CH 3) branch, the word root "-pent-" is derived from the fact that there are 5 carbon atoms in the parent chain, while the "-ene" suffix denotes that there is a double bond present, as per IUPAC nomenclature.

The Lemieux–Johnson reaction ceases at the aldehyde stage of oxidation and therefore produces the same results as ozonolysis. The classical Lemieux–Johnson oxidation often generates many side products, resulting in low reaction yields; however the addition of non-nucleophilic bases, such as 2,6-lutidine, can improve on this.

The oxime first reacts with the ozone to form the corresponding carbonyl oxide, undergoes 1,3-dipolar cycloaddition with the carbonyl reactant to form the cyclic ozonide, as usual for the Criegee intermediate in the ozonolysis of alkenes. If no carbonyl compound is used, the carbonyl oxide may dimerize and form 1,2,4,5-tetraoxanes.
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
This net reaction can also be described as follows: [PdCl 4] 2 − + C 2 H 4 + H 2 O → CH 3 CHO + Pd + 2 HCl + 2 Cl −. This conversion is followed by reactions that regenerate the Pd(II) catalyst: Pd + 2 CuCl 2 + 2 Cl − → [PdCl 4] 2− + 2 CuCl 2 CuCl + 1 / 2 O 2 + 2 HCl → 2 CuCl 2 + H 2 O. Only the alkene and oxygen are consumed.
Hydrogen peroxide (H 2 O 2) can be used as HOCl scavenger whose byproducts do not interfere in the Pinnick oxidation reaction: HOCl + H 2 O 2 → HCl + O 2 + H 2 O. In a weakly acidic condition, fairly concentrated (35%) H 2 O 2 solution undergoes a rapid oxidative reaction with no competitive reduction reaction of HClO 2 to form HOCl. HClO 2 ...
