Reactive GroupMetal Hydrides, Metal Alkyls, Metal Aryls, and Silanes
Reactivity AlertsStrong Reducing Agent
Reactivity Profile
Hydrides, such as MAGNESIUM DIPHENYL, are reducing agents and react rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Thus, they are likely to ignite on contact with alcohols. Hydrides are incompatible with acids, alcohols, amines, and aldehydes.
Air and Water Reactions
Highly flammable. Soluble in water. May spontaneously ignite upon exposure to air. Dialkyl derivatives of magnesium have been known to explode on contact with water and will glow and catch fire even in atmosphere of carbon dioxide [Merck 11th ed. 1989].
