There are three main types of pyrophoric agents white phosphorus and other inorganic non metals, finely divided metals, and certain organometallic compds... 

Reacts with many metals to give hydrogen, sometimes violently. With non-metals pyrophoric hydrides may result. Frequently initiates explosive reactions between other substances. Violent reactions with many non-metal and some metal halides and oxyhalides, also with many organometallic compounds. Many metal nonmetal-lides produce toxic, flammable or pyrophoric gases on contact with diprotium monoxide. 

The organometallic compounds of the heavier alkali metals are in general extremely air- and moisture-sensitive and many are highly pyrophoric. Great care is necessary in their manipulation. 

Aluminium Alkyls and other Organometallics, 5, New York, Ethyl Corp., 1967 It is immediately pyrophoric in air.

This compound was pyrophoric even as arelatively dilute pentane solution (Editor s Note This was a crude preparation probably containing many other organometallics). 

This, like other transition metal carbonyl derivatives of magnesium, is pyrophoric. See other CARBONYLMETALS, ORGANOMETALLICS... 

Class D fires involve combustible metals, such as magnesium, titanium, potassium and sodium as well as pyrophoric organometallic reagents such as alkyllithiums, Grignards and diethylzinc. These materials burn at high temperatures and will react violently with water, air, and/or other chemicals. Handle with care ... 

Compounds of these metals involving either a- or tt-bonds to carbon are generally much more reactive to both air and water than those of the d-block metals. Thus there is no lanthanide equivalent of ferrocene, an unreactive air- and heat-stable compound. They are often thermally stable to 100 °C or more, but are usually decomposed immediately by air (and are not infrequently pyrophoric). Within these limitations, lanthanide organometallic compounds have their own special features, often linked with the large size of these metals. 

Although lacking 7T-bonded compounds in low oxidation states that characterize the d-block elements, the actinides have a rich organometallic chemistry. Their compounds frequently exhibit considerable thermal stability, but like the lanthanide compounds are usually intensely air- and moisture-sensitive. They are often soluble in aromatic hydrocarbons such as toluene and in ethers (e.g., THF) but are generally destroyed by water. Sometimes they are pyrophoric on exposure to air. Most of the synthetic work has been carried out with Th and U this is partly due to the ready availability of MCI4 (M = Th, U) and also because of the precautions that have to be taken in handling compounds of other metals, especially Pu and Np.
