Dear Sir/Ma'am

How can 2,3-DehydroCycloHexanol's (-OH) group be turned into a Methylene group (=CH2) to create 2,3-Dehydro MethyleneCyclohexane???

Dehydro means that there's a double bond (they miss one Hydrogen each) between the atoms specified (2,3 for this molecule)!

Yes, it is possible to make such a reagent from the corresponding bromide, which is commercially available. (CAS 1779-49-3).

Ready-made Wittig reagent should also be available commercially, althouh I think it's better to make it in situ yourself.
