There are 51 chemical datasheets assigned to this reactive group.

What are reactive groups?

Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure. Each substance with a chemical datasheet has been assigned to one or more reactive groups, and CAMEO Chemicals uses the reactive group assignments to make its reactivity predictions. More info about reactivity predictions...

If you can't find a chemical in the database--but you know what reactive group it belongs in--you can add the reactive group to MyChemicals instead in order to see the reactivity predictions.

Flammability
Many of the compounds in this group may be highly flammable. Those that are gases are explosive.
Reactivity
Dienes exhibit unique chemistry such as the Diels-Alder reaction (specifically, a cycloaddition) between a conjugated diene and a substituted alkene, commonly termed the dienophile, to form a substituted cyclohexene system. The reaction can proceed even if some of the atoms in the newly formed ring are not carbon. Butadiene can be oxidized to form explosive peroxides. Many dienes can be induced into polymerization reactions by initiation by acids, bases, metal ions, various metal/organometallic species with the release of large amounts of energy as heat.
Toxicity
Not toxic, except as gases that can exclude oxygen in breathing zone during accident.
Other Characteristics
Dienes form a class of compounds that possess conjugated carbon-carbon double bonds. Butadiene is the classic diene and is vital to the formulation of many polymers.
Examples
Abamectin, cycloheptatriene, mezerein, octadiene, sulfan blue, butadiene, pentadiene.
