WebThe technical product often ignites spontaneously at room temperature because of the presence of other phosphorus hydrides, especially diphosphine (CAS:13445-5-6) as impurities. Odourless when pure at concentrations up to 200 ppm (278 mg/m 3) (a highly toxic level). Technical product has odour of garlic or decaying fish due to impurities. WebThe phosphine is also easily alkylated. For example, benzyl chloride gives the phosphonium salt: [2] PBu 3 + PhCH 2 Cl → [PhCH 2 PBu 3 ]Cl. Tributylphosphine is a common ligand for the preparation of complexes of transition metals in low oxidation states. It is cheaper and less air-sensitive than trimethylphosphine and other trialkylphosphines.
