AbstractAzide compounds are widely used and especially, polymers bearing pendant azide groups are highly desired in numerous fields. However, harsh reaction conditions are always mandatory to achieve full azidation, causing severe side reactions and degradation of the polymers.

Hydrazine hydrate (1.67 ml = 1.72 g, 34 mmol) is added to a solution of N-benzyloxycarbonyl-S-benzyl-l-cysteinyl-l-seryl-l-histidine methyl ester [1, 2] (5.84 g, 10 mmol) in methanol [3] (50 ml) and the reaction mixture is kept at room temperature for 3 days [4].

Starch is an inexpensive commodity that has been used for non-food purposes for many years. Some of these uses include cross-linked starches that are synthesized with a variety of multifunctional reagents. One unexplored possibility is the use of azides for cross-linking.

AbstractPure, solvent‐free Zn(N3)2 was prepared by reaction of diethyl zinc and hydrazoic acid in aprotic solvents. The single‐crystal structure determination, along with the comprehensive characterization of α‐Zn(N3)2 and two metastable polymorphs, could be achieved for the first time.

Structure of azide methemoglobin
Journal of Molecular Biology, 1979Abstract We have compared the structures of horse azide methemoglobin and methemoglobin (MetHb) at 2.8 A resolution by X-ray difference Fourier analysis. Of four low-spin liganded Hb derivatives (nitric oxide Hb, carbon monoxide Hb, cyanide MetHb, and azide MetHb), azide MetHb is closest in structure to MetHb.

Sensitized photodecomposition of phenyl azide and α-naphthyl azide
J. Chem. Soc., Faraday Trans. 2, 1972The photodecomposition of phenyl azide and α-naphthyl azide can be induced by triplet sensitizers (aromatic ketones) and by singlet sensitizers (aromatic hydrocarbons). From a comparison of transfer rates with sensitizer energies, and from the spectra and the oxidation potentials of the azides, it appears that two different mechanisms may operate ...

Publisher Summary This chapter discusses glycosyl fluorides and their derivatives and glycosyl azides and carbohydrates containing fluorine at nonglycosidic carbon atoms. Poly- O -acetylglycosyl halides of the carbohydrates investigate the proportionality relations that exist between the optical rotations and the diameters of the respective halogen ...
