The main use of ozonolysis is for the conversion of unsaturated fatty acids to value-added derivatives. 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
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.

As of 2010s, the only commercial manufacturer of 1-pentene was Sasol Ltd., where it is separated from crude by the Fischer-Tropsch process. [2] 2-Pentene has two geometric isomers: cis-2-pentene and trans-2-pentene. Cis-2-Pentene is used in olefin metathesis.
[2] [3] [4] Acyclic alkenes, with only one double bond and no other functional groups (also known as mono-enes) form a homologous series of hydrocarbons with the general formula C n H 2n with n being a >1 natural number (which is two hydrogens less than the corresponding alkane).
Isomers with the molecular formula C 5 H 10 with CAS numbers C 5 H 10 is the molecular formula of 13 hydrocarbon isomers (represented by their CAS numbers on the chart). They can be divided into cycloalkanes and alkenes .
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.
The epoxide is opened at the least hindered end with 1-methyl-1H-tetrazole-5-thiol to put in place the future C-3 side chain and give intermediate 5. Jones oxidation followed in turn by ozonolysis (reductive work-up with zinc-AcOH) and reaction with SOCl2 and pyridine give halide 6. The stage is now wet for intramolecular Wittig reaction.
For example, the relative rates of epoxidation increase upon methyl substitution of the alkene (the methyl groups increase the electron density of the double bond by hyperconjugation): ethylene (1, no methyl groups), propene (24, one methyl group), cis-2-butene (500, two methyl groups), 2-methyl-2-butene (6500, three methyl groups), 2,3 ...
