tBu3P
tBu3P, also known as tri-tert-butylphosphine, is an organophosphorus compound with the chemical formula P(C(CH3)3)3. It is a tertiary phosphine and is characterized by its bulky tert-butyl groups attached to the phosphorus atom. This steric bulk significantly influences its chemical properties and reactivity.
Tri-tert-butylphosphine is a white, crystalline solid at room temperature and is air-sensitive, often requiring handling under
In catalysis, tBu3P is widely employed as a ligand, particularly in palladium-catalyzed cross-coupling reactions such as
