Most methylcyclohexane is extracted from petroleum but it can be also produced by catalytic hydrogenation of toluene: CH 3 C 6 H 5 + 3 H 2 → CH 3 C 6 H 11. Methylcyclohexane, as a component of a mixture, is usually dehydrogenated to toluene, which increases the octane rating of gasoline.
It can be produced by a Wittig reaction or a reaction with a Tebbe's reagent from cyclohexanone. [1] [2] [3] It can also be synthesized as a side product of the dehydration of 2-methylcyclohexanol into 1-methylcyclohexene.
Oxidation of 1-methylcyclohexene catalyzed by cytochrome P450 yields a 2:1 mixture of hydroxylation to epoxidation products. [4] The stereochemistry of hydroformylation has been examined using 1-methylcyclohexene. The main product has the formyl group on the less substituted alkene-carbon, trans with respect to the methyl substituent.
The process, which is catalyzed by platinum supported by aluminium oxide, is exemplified in the conversion methylcyclohexane (a naphthene) into toluene (an aromatic). [2] Dehydrocyclization converts paraffins (acyclic hydrocarbons) into aromatics. [3] A related aromatization process includes dehydroisomerization of methylcyclopentane to benzene:

In the presence of a Cinchona alkaloid, bromination of an alkene can leads to optically active dibromides. [2] For 4-methylcyclohexene, the ( S )-configuration leads to two different products: the bromines can add at the axial positions, giving the orientation (1 S ,3 R ,4 R ), or at the equatorial positions, giving the orientation (1 S ,3 S ,4 ...
[10] [11] The entire circuit is known as the Methylcyclohexane-Toluene-Hydrogen system (MTH). [12] Gravimetric hydrogen storage densities of methylcyclohexane and toluene (MCH-TOL) are 6.1 wt%, or volumetric hydrogen storage densities at 47 kg/m 3 in ambient conditions, [13] [14] corresponding to 5.5 MJ/L hydrogen. [15]
They are named analogously to their normal alkane counterpart of the same carbon count: methylcyclopropane, methylcyclobutane, methylcyclopentane, methylcyclohexane, etc. [1] Methylcycloalkanes are classed into compounds with small, normal and bigger cycloalkanes, where cyclopropane and cyclobutane are the small ones, cyclopentane , cyclohexane ...
