WebDienes are prepared from the same reactions that form ordinary alkenes. The two most common methods are the dehydration of diols (dihydroxy alkanes) and the dehydrohalogenation of dihalides (dihaloalkanes). The generation of either an isolated or conjugated system depends on the structure of the original reactants.
