  2. Phosphoryl bromide - Wikipedia

    en.wikipedia.org/wiki/Phosphoryl_bromide

    Phosphoryl bromide is prepared by the reaction between phosphorus pentabromide and phosphorus pentoxide: [4] [5]. 3 PBr 5 + P 2 O 5 → 5 POBr 3. It can also be prepared via the slow addition of liquid bromine to phosphorus tribromide at 0 °C, followed by the slow addition of water and vacuum distillation of the resulting slurry.

  3. Phosphoryl chloride - Wikipedia

    en.wikipedia.org/wiki/Phosphoryl_chloride

    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 ]

    The unusual linear M−O−M structure can be rationalized in terms of molecular orbital theory, indicating the presence of d π — p π bonding between the metal and oxygen atoms. [20] Oxygen bridges are present in more complex configurations like M(cp) 2 (OTeF 5 ) 2 (M = Ti, Zr, Hf, Mo or W; cp = cyclopentadienyl , η 5 -C 5 H 5 ) [ 21 ] or ...

  5. Phosphorus tribromide - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_tribromide

    PBr 3 is prepared by treating red phosphorus with bromine. An excess of phosphorus is used in order to prevent formation of PBr 5: [1] [2] P 4 + 6 Br 2 → 4 PBr 3. Because the reaction is highly exothermic, it is often conducted in the presence of a diluent such as PBr 3. Phosphorus tribromide is also generated in situ from red phosphorus and ...

    en.wikipedia.org/wiki/Phosphorus_halide

    Phosphorus(II) halides may be prepared by passing an electric discharge through a mixture of the trihalide vapour and hydrogen gas. [ citation needed ] The relatively stable P 2 I 4 is known to have a trans , bent configuration similar to hydrazine and finds some uses in organic syntheses, the others are of purely academic interest at the ...

    Tetrapolyphosphoric acid H 6 P 4 O 13 yields at least six anions, including tetrapolyphosphate [P 4 O 13] 6−, and so on. Note that each extra phosphoric unit adds one extra P atom, three extra O atoms, and either one extra hydrogen atom or an extra negative charge. Branched polyphosphoric acids give similarly branched polyphosphate anions.

    Those with five organic substituents are rare, although P(C 6 H 5) 5 is known, being derived from P(C 6 H 5) 4 + by reaction with phenyllithium. [citation needed] Phosphorus ylides are unsaturated phosphoranes, known as Wittig reagents, e.g. CH 2 P(C 6 H 5) 3. These compounds feature tetrahedral phosphorus(V) and are considered relatives of ...
