In recent times the catalytic oxidation of cyclohexene by (immobilized) metalloporphyrin complexes has been found to be an efficient way. [7] [8] In laboratory, cyclohexene oxide can also be prepared by reacting cyclohexene with magnesium monoperoxyphthalate (MMPP) in a mixture of isopropanol and water as solvent at room temperature. [9]
Cyclohexene derivatives, such as imines, epoxides, and halonium ions, react with nucleophiles in a stereoselective fashion, affording trans-diaxial addition products. The term “Trans-diaxial addition” describes the mechanism of the addition, however the products are likely to equilibrate by ring flip to the lower energy conformer, placing the new substituents in the equatorial position.
For cyclohexane, cyclohexene, and cyclohexadiene, dehydrogenation is the conceptually simplest pathway for aromatization. The activation barrier decreases with the degree of unsaturation. Thus, cyclohexadienes are especially prone to aromatization. Formally, dehydrogenation is a redox process. Dehydrogenative aromatization is the reverse of ...
Benzene is converted to cyclohexylbenzene by acid-catalyzed alkylation with cyclohexene. [6] Cyclohexylbenzene is a precursor to both phenol and cyclohexanone. [7] Hydration of cyclohexene gives cyclohexanol, which can be dehydrogenated to give cyclohexanone, a precursor to caprolactam. [8] The oxidative cleavage of cyclohexene gives adipic acid.
The volatile dioxiranes DMD and TFD can be isolated via distillation. Once isolated, dioxiranes can be kept in solutions of the corresponding ketones and dried with molecular sieves. These solutions are suitable when substrates or products are sensitive to hydrolysis. [17] Catalytic dioxirane oxidations do, however, require water.
4-Vinylcyclohexene is an organic compound consisting of a vinyl group attached to the 4-position of the cyclohexene ring. It is a colorless liquid. Although chiral, it is used mainly as the racemate. It is a precursor to vinylcyclohexene dioxide. [4]
1-Methylcyclohexene an organic compound consisting of cyclohexene with a methyl group substituent attached to the alkene group. Two other structural isomers are known: 3-methylcyclohexene and 4-methylcyclohexene. All are colorless volatile liquids. They are specialized reagents.
The general structure of an organic peroxide. In organic chemistry, organic peroxides are organic compounds containing the peroxide functional group (R−O−O−R′).If the R′ is hydrogen, the compounds are called hydroperoxides, which are discussed in that article.
