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.
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.
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 ...
Methyl phenyldiazoacetate is prepared by treating methyl phenylacetate with p-acetamidobenzenesulfonyl azide in the presence of base. [2] [3] Solid state structure of t-BuO 2 CC(N 2)C 6 H 4 NO 2, a representative donor-acceptor carbene related to the title compound. Key distances: C-N = 1.329 Å, N-N = 1.121 Å.
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 ...
