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.
The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
Bisphenol A diphenyl phosphate is a halogen-free flame retardant used plastics. It is used in polymer blends of engineering plastics, such as PPO/HIPS and PC/ABS, [1] which are commonly used to make casing for electrical items like TVs, computers and home appliances. It is formed by the transesterification of bisphenol A with triphenyl phosphate.
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°.
2-Ethylhexyl diphenyl phosphate (Octicizer) is an organophosphate compound. It acts as both a plasticizer and flame retardant in PVC, its wide liquid range also makes it suitable as a flame retardant in hydraulic fluids. It has low acute toxicity in feeding experiments, [1] but has been implicated as a potential hormone mimetic. [2] [3]
The phosphate sulfates are mixed anion compounds containing both phosphate and sulfate ions. Related compounds include the arsenate sulfates , phosphate selenates , and arsenate selenates . Some hydrogen phosphate sulfates are superprotonic conductors .
