Phosphorus pentachloride is the chemical compound with the formula PCl 5. It is one of the most important phosphorus chlorides/oxychlorides, others being PCl 3 and POCl 3. PCl 5 finds use as a chlorinating reagent. It is a colourless, water-sensitive solid, although commercial samples can be yellowish and contaminated with hydrogen chloride.
Phosphorus pentachloride, phosphorus pentabromide, and phosphorus heptabromide are ionic in the solid and liquid states; PCl 5 is formulated as PCl 4 + PCl 6 –, but in contrast, PBr 5 is formulated as PBr 4 + Br −, and PBr 7 is formulated as PBr 4 + Br 3 −. They are widely used as chlorinating and brominating agents in organic chemistry.
A pentachloride is a compound or ion that contains five chlorine atoms or ions. Common pentachlorides include: Antimony pentachloride, SbCl 5; Arsenic pentachloride, AsCl 5; Molybdenum pentachloride, MoCl 5; Niobium pentachloride, NbCl 5; Phosphorus pentachloride, PCl 5; Protactinium pentachloride, PaCl 5; Osmium pentachloride, OsCl 5; Rhenium ...
Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula P O Cl 3. It hydrolyses in moist air releasing phosphoric acid and fumes of hydrogen chloride. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. [4] It is mainly used to make ...
For phosphorus pentachloride as an example, the phosphorus atom shares a plane with three chlorine atoms at 120° angles to each other in equatorial positions, and two more chlorine atoms above and below the plane (axial or apical positions).
The most common phosphonium compounds have four organic substituents attached to phosphorus. The quaternary phosphonium cations include tetraphenylphosphonium, (C 6 H 5) 4 P + and tetramethylphosphonium P(CH 3) + 4. Tetramethylphosphonium bromide [3] Structure of solid "phosphorus pentachloride", illustrating its autoionization to ...
Crystalline samples have been produced by the reaction of ammonium chloride and hexachlorocyclotriphosphazene [4] or phosphorus pentachloride. [1] (NPCl 2) 3 + 2 [NH 4]Cl → P 3 N 5 + 8 HCl 3 PCl 5 + 5 [NH 4]Cl → P 3 N 5 + 20 HCl. P 3 N 5 has also been prepared at room temperature, by a reaction between phosphorus trichloride and sodium ...
French researcher, Alexandre Baudrimont prepared sodium phosphide by treating molten sodium with phosphorus pentachloride. [5] 8 Na (l) + PCl 5 → 5 NaCl + Na 3 P. Many different routes to Na 3 P have been described. Due to its flammability and toxicity, Na 3 P (and related salts) is often prepared and used in situ.
