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 ...
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.

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°.
Sodium nitrate is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate.
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.
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]
Silver azide can be prepared by treating an aqueous solution of silver nitrate with sodium azide. [2] The silver azide precipitates as a white solid, leaving sodium nitrate in solution. AgNO 3 + NaN 3 (aq) → AgN 3 + NaNO 3 (aq) X-ray crystallography shows that AgN 3 is a coordination polymer with square planar Ag + coordinated by four azide ...
