Methylenecyclohexane (IUPAC name: methylidenecyclohexane) is an organic compound with the molecular formula C7H12.
Synthesis
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.
Structure
Methylenecyclohexane is an unsaturated hydrocarbon, containing a cyclohexane ring with a methylene (methylidine) group attached.

I this way, cyclohexanone is transformed into methylenecyclohexene and benzaldehyde into stryene.

Now, when cyclohexanone is added to the solution in which the [Tebbe] reagent has been generated, reaction occurs to produce methylenecyclohexane and triphenylphosphine oxide
