  2. Diphenylphosphoryl azide - Wikipedia

    en.wikipedia.org/wiki/Diphenylphosphoryl_azide

    It is now suggested that this reaction proceeds through the intermediate mixed anhydride, resulting from attack by the nucleophilic carboxylate anion on the phosphorus atom, with expulsion of the azide ion. The latter then attacks the carbonyl carbon atom, to give the acyl azide and loss of the diphenylphosphate anion, known to be a good ...

  3. Organic azide - Wikipedia

    en.wikipedia.org/wiki/Organic_azide

    The azide functional group can be shown by two resonance structures. An organic azide is an organic compound that contains an azide (– N 3) functional group. [1] Because of the hazards associated with their use, few azides are used commercially although they exhibit interesting reactivity for researchers.

    It can be prepared by reaction of phosphoric acid with phosphoryl chloride: [2]. 5 H 3 PO 4 + POCl 3 → 3 H 4 P 2 O 7 + 3 HCl. It can also be prepared by ion exchange from sodium pyrophosphate or by treating lead pyrophosphate with hydrogen sulfide.

  6. Phenyl azide - Wikipedia

    en.wikipedia.org/wiki/Phenyl_azide

    Phenyl azide is an organic compound with the formula C 6 H 5 N 3. It is one of the prototypical organic azides. It is a pale yellow oily liquid with a pungent odor. The structure consists of a linear azide substituent bound to a phenyl group. The C−N=N angle is approximately 116°.

  7. Chlorodiphenylphosphine - Wikipedia

    en.wikipedia.org/wiki/Chlorodiphenylphosphine

    Chlorodiphenylphosphine is used in the synthesis of sodium diphenylphosphide via its reaction with sodium metal in refluxing dioxane. [5] Ph 2 PCl + 2 Na → Ph 2 PNa + NaCl. Diphenylphosphine can be synthesized in the reaction of Ph 2 PCl and LiAlH 4, the latter usually used in excess. [6] 4 Ph 2 PCl + LiAlH 4 → 4 Ph 2 PH + LiCl + AlCl 3

  8. Tosyl azide - Wikipedia

    en.wikipedia.org/wiki/Tosyl_azide

    Tosyl azide is one of the most stable azide compounds but is still regarded as a potential explosive and should be carefully stored, while particular caution is vital for all reactions in which it is heated at or above 100 °C. The initial temperature of the explosive decomposition is about 120 °C. [1]

  9. 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] It is mainly used to make ...
