Reactive Group Datasheet


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.

There are 73 chemical datasheets assigned to this reactive group.


Many organometallic compounds are flammable or highly flammable; sometimes they are pyrophoric. They are generally combustible.
A diverse group of compounds are classified as organometallics, and the reactivity of this group varies widely. They are strongly reactive with many other groups, and incompatible with acids and bases. Organometallics are often fair reducing agents and therefore incompatible with oxidizing agents. Many react with water to generate toxic or flammable gases. Organometallics containing halogens (fluorine, chlorine, bromine, iodine) bonded to the metal typically will generate gaseous hydrohalic acids (HF, HCl, HBr, HI) with water, with heat released.
Generally highly toxic. Often react on contact with tissues to give toxic products. Irritating to skin, eyes, and mucous membranes. Can damage lung tissue and the liver.
Other Characteristics
These compounds contain carbon bonded directly to a transition metal. This means that metallic carbonates are excluded and also metallic salts of carboxylic acids and other organic acids. Many chlorosilanes can be regarded as organometallic. However, these compounds are listed in the Chlorosilanes group.
Bis(1,5-cyclooctadiene)nickel, bis(cyclopentadienyl)chromium, bis(cyclopentadienyl)vanadium chloride, bis(cyclopentadienyl)vanadium dichloride, bis(tributyltin)oxide, chromium carbonyl, cobalt carbonyl, cobaltocene, dibutyltin diacetate.
