Diene - Wikipedia
网页In organic chemistry, a diene (/ ˈ d aɪ iː n / DY-een); also diolefin, / d aɪ ˈ oʊ l ə f ɪ n / dy-OH-lə-fin) or alkadiene) is a covalent compound that contains two double bonds, usually among carbon atoms. [1] They thus contain two alkene units, with the standard prefix di of systematic nomenclature.

网页2023年1月23日 · We find significant differences in the chemical properties of dienes depending on their structural type. For example, catalytic hydrogenation converts all the dienes shown here to the alkane hexane, but the heats of reaction (heat of hydrogenation) reflect characteristic differences in their thermodynamic stability.
