Bretherick’s Handbook of Reactive Chemical Hazards
Phase: solid, liquid or gas

Liquids: “ examples

Alkylaluminum reagents (Neat or in hydrocarbon solvents) (Neat reagents are VERY pyrophoric)

Alkyllithium reagents (Typically in hydrocarbon solvents) (Tert-butyllithium is VERY pyrophoric)

Alkenyllithium and Aryllithium reagents (Typically in hydrocarbon solvents)

Alkynyllithium reagents (Typically in hydrocarbon solvents)

Alkylzinc reagents (Neat reagents are pyrophoric)

Boranes (Neat reagents are pyrophoric)

Grignard Reagents (RMgX) (Typically in hydrocarbon solvents)

Partially or fully alkylated derivatives of metal and nonmetal hydrides (diethylaluminium hydride,diisobutylaluminum hydride, dichloro(methyl)silane) (Usually in liquid form or in solution.)

Alkylated metals (butyllithium, triethylboron, trimethylaluminum) (Usually in liquid form or in solution.)

Non-metal alkyls: R3B, R3P, R3As; Tetramethylsilane, Tributylphosphine”

Metal alkyls and aryls, such as RLi, RNa, R3Al, R2Zn

UCLA

Solids:

Alkali metals (lithium, sodium, potassium, especially sodium potassium alloy – NaK, and even more dangerous are cesium and rubidium)

Alkylated metal alkoxides or halides (dimethylaluminum chloride, diethylethoxyaluminium)

Finely divided metals (bismuth, calcium, hafnium, iron, magnesium, titanium, uranium, zirconium) Al, Co, Fe, Mg, Mn, Pd, Pt, Ti, Sn, Zn, Zr

Low valent metals (titanium dichloride)

Metal hydrides (potassium hydride, sodium hydride, lithium aluminum hydride, uranium trihydride NaH, LiAlH4)

Nonmetals (white phosphorous)

Metal carbonyls (dicobalt octacarbonyl, nickel carbonyl) Ni(CO)4, Fe(CO)5, Co2(CO)8

Used hydrogenation catalysts, e.g. Raney Ni, are especially hazardous due to adsorbed hydrogen gas

Copper fuel cell catalysts, e.g. Cu/ZnO/Al2O3 Methanetellurol (CH3TeH)

Finely divided Iron sulfides (FeS, FeS2, Fe3S4), Potassium sulfide (K2S), Aluminum phosphide (AlP)” UCLA

Gases:

Nonmetal hydrides (arsine, boranes, germane, phosphine, silane) (Most of these are actually gases.) B2H6 and other boranes, PH3, AsH3
