Alkyl and Aryl Azides.

Structures and molecular surface electrostatic potentials of high-density C, N, H systems

“…The minima associated with the nitrogens, both Vs. rain(N) and Vmin(N), are listed in Table III. An interesting feature of these results is the charge distribution in the azido group. Table III 13A 13B 13C structural data in Table I, as well as with earlier interpretations [32]. Table III also reveals the ring nitrogens in 5 to be more negative than in 6.…”

Synthesis of amines by the electrophilic amination of organomagnesium, -zinc, -copper, and -lithium reagents

“…[66][67][68][69] Various azides were used for the electrophilic amination of organomagnesium reagents.…”

Orientation and Relative Reaction Rate Factors in Aromatic Substitution by the Benzenesulfonimido Radical

“…Other special methods (21) have been reperted, such as addition of hydrazoic acid to olefins, rearrangements such as the Hofmann, basic cleavage of tetrazoles and dihydrotetrazoles, and direct methylation of hydrazoic acid with diazomethane, but these methods are not of general preparative interest.…”

“…Curtius (31) observed that HN 3 was obtained by action of dilute H 2 so 4 upon aliphatic azides such as azidoacetic acid or benzyl azide (21). More recently, the isolation of trace amounts of acetanilide from a mixture of methyl azide, acetophenone and concentrated sulfuric acid, has indicated a transitory existence of hydrazoic acid from hydrolysis (21,110 predominates.…”

“…This reaction has proved to be of very general usefulness since not only halogens, but sulfate, nitro, phenylazo, hydroxyl, nitrate, iodoxy and alkoxy groups also have been found to be displaced by the use of metallic or hydrogen azides (21).…”
