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°.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Like trifluoromethanesulfonyl azide, this compound generally converts primary amines or ammonium salts to azides when catalyzed by copper(II), nickel(II), zinc(II), and cobalt(II) salts. [2] This reaction is effectively the reverse of the Staudinger reaction. Similarly, it is able to transfer the diazo group (=N 2) under basic conditions. [2]
Iron(III) azide, also called ferric azide, is a chemical compound with the formula Fe(N 3) 3. It is an extremely explosive, impact-sensitive, hygroscopic dark brown solid. This compound is used to prepare various azidoalkanes, such as n -butyl azide, from alkenes via formation of alkylboranes and subsequent anti-Markovnikov addition of azide group.
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]
