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 is produced by the partial hydrogenation of benzene, a process developed by the Asahi Chemical company. [4] The main product of the process is cyclohexane because cyclohexene is more easily hydrogenated than benzene. In the laboratory, it can be prepared by dehydration of cyclohexanol. [5] C 6 H 11 OH → C 6 H 10 + H 2 O
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.

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.
4-Methylcyclohexene is an organic compound consisting of cyclohexene with a methyl group substituent attached to carbon most distant from the alkene group. Two other structural isomers are known: 1-methylcyclohexene and 3-methylcyclohexene. All are colorless volatile liquids classified as a cyclic olefins. They are specialized reagents.
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]
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 ...
