  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.

  4. 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°.

  5. Diphenylphosphite - Wikipedia

    en.wikipedia.org/wiki/Diphenylphosphite

    Diphenyl phosphite is a diorganophosphite with the formula (C 6 H 5 O) 2 P(O)H. The molecule is tetrahedral. It is a colorless viscous liquid. The compounds can be prepared by treating phosphorus trichloride with phenol. Many analogues can be prepared similarly.

  6. Pyrophosphoric acid - Wikipedia

    en.wikipedia.org/wiki/Pyrophosphoric_acid

    Pyrophosphoric acid, also known as diphosphoric acid, is the inorganic compound with the formula H 4 P 2 O 7 or, more descriptively, [(HO) 2 P(O)] 2 O. Colorless and odorless, it is soluble in water, diethyl ether, and ethyl alcohol.

  7. Diazodinitrophenol - Wikipedia

    en.wikipedia.org/wiki/Diazodinitrophenol

    Diazodinitrophenol (DDNP) was the first diazo compound produced; it was subsequently used to make dyes and explosives. It forms yellow crystals in pure form; however, the color of impure forms may vary from dark yellow to green to dark brown. [1]

  8. 2-Nitrodiphenylamine - Wikipedia

    en.wikipedia.org/wiki/2-Nitrodiphenylamine

    2-Nitrodiphenylamine is an organic chemical with the formula C 6 H 5 NHC 6 H 4 NO 2. It is a nitrated derivative of diphenylamine. It is a red solid, usually found in form of flakes or powder. It is polar but hydrophobic. Diphenylamine is used to extend the shelf-life of explosives containing nitrocellulose or nitroglycerin. Such nitrated ...

  9. 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]
