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°.
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.
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 ]
Diphenyl-2-pyridylphosphine is an organophosphorus compound with the formula P(C 6 H 5) 2 (2-C 5 H 4 N). It is the most widely used mono-pyridylphosphine ligand. [1] Other mono-pyridylphosphines ligands (3-, 4-) are not common in chemical literature; however, tris-pyridylphosphines have been thoroughly investigated as ligands in transition metal complexes used for catalysis.
Chlorodiphenylphosphine is an organophosphorus compound with the formula (C 6 H 5) 2 PCl, abbreviated Ph 2 PCl. It is a colourless oily liquid with a pungent odor that is often described as being garlic-like and detectable even in the ppb range.
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.
