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.
It has also been found in other plants and foods such as tomatoes, cocoa, tea, and potato chips. [5] 3-Penten-2-one can be used for the synthesis of other compounds such as the alkaloids senepodine G and cermizine C, for example. [7] It is also a useful flavoring agent. [5]
Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
A simple example of cis–trans isomerism is the 1,2-disubstituted ethenes, like the dichloroethene (C 2 H 2 Cl 2) isomers shown below. [7] Dichloroethene isomers. Molecule I is cis-1,2-dichloroethene and molecule II is trans-1,2-dichloroethene.
For example, there are two isomers of square planar Pt(NH 3) 2 Cl 2, as explained by Alfred Werner in 1893. The cis isomer, whose full name is cis -diamminedichloroplatinum(II), was shown in 1969 by Barnett Rosenberg to have antitumor activity, and is now a chemotherapy drug known by the short name cisplatin .
For example, butanol H 3 C−(CH 2) 3 −OH, methyl propyl ether H 3 C−(CH 2) 2 −O−CH 3, and diethyl ether (H 3 CCH 2 −) 2 O have the same molecular formula C 4 H 10 O but are three distinct structural isomers. The concept applies also to polyatomic ions with the same total charge. A classical example is the cyanate ion O=C=N − and ...
Methylene-interrupted polyenes are 1,4-pentadiene groups found in polyunsaturated fatty acids linoleic acid, α-linolenic acid, and arachidonic acid.These pentadiene derivatives are susceptible to lipid peroxidation, far moreso than monounsaturated or saturated fatty acids.
Insect pheromones are produced by a variety of exocrine glands consisting primarily of modified epidermal cells at various sites on the insect body. For example, the abdominal glands of the female silkmoth release traces of the (E,E)-isomer of alcohol as well as the analogous (E,Z)-aldehyde bombycal, in addition to the sex pheromone bombycol.
