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. The conversion entails ozonolysis, which selectively cleaves the C=C bond in erucic acid: [21]
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 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.
3-Methyl-3-penten-2-one is an unsaturated aliphatic ketone. It is an isomer of mesityl oxide and isomesityl oxide. It is a precursor of 3-methyl-2-pentanone (methyl sec-butyl ketone) and is obtained by acid-catalyzed dehydration of 4-hydroxy-3-methyl-2-pentanone. It is used as an intermediate in organic chemistry syntheses. [1]
