EPR and pulsed ENDOR study of intermediates from reactions of aromatic azides with group 13 metal trichlorides [PDF]

Beilstein Journal of Organic Chemistry, 2010
The reactions of group 13 metal trichlorides with aromatic azides were examined by CW EPR and pulsed ENDOR spectroscopies. Complex EPR spectra were obtained from reactions of aluminium, gallium and indium trichlorides with phenyl azides containing a ...

Lattice dynamics and electronic structure of energetic solids LiN3 and NaN3: A first principles study [PDF]

Chemical Physics Letters, Volume 586, Page no 44 (2013), 2013
We report density functional theory calculations on the crystal structure, elastic, lattice dynamics and electronic properties of iso-structural layered monoclinic alkali azides, LiN3 and NaN3. The effect of van der Waals interactions on the ground- state structural properties is studied by using various dispersion corrected density functionals.

Iron Corrole‐Catalyzed Intramolecular Amination Reactions of Alkyl Azides. Spectroscopic Characterization and Reactivity of [FeV(Cor)(NAd)] [PDF]

Advanced Science
As nitrogen analogues of iron‐oxo species, high‐valent iron‐imido species have attracted great interest in the past decades. FeV‐alkylimido species are generally considered to be key reaction intermediates in Fe(III)‐catalyzed C(sp3)─H bond aminations of

The inhibition of caeruloplasmin by azide [PDF]

Biochemical Journal, 1966
1. The inhibition of the oxidase activity of caeruloplasmin by azide was investigated at 25 degrees and 7.5 degrees . 2. The inhibition is reversible on dilution or Sephadex treatment, indicating a caeruloplasmin-azide complex. 3. The enzyme is protected against azide inhibition by chloride, acetate or EDTA, the last-named acting not by chelation but ...

Metal-free double azide addition to strained alkynes of an octadehydrodibenzo[12]annulene derivative with electron-withdrawing substituents [PDF]

Beilstein Journal of Organic Chemistry
Strain-promoted azide–alkyne cycloaddition (SpAAC) is a powerful tool in the field of bioconjugation and materials research. We previously reported a regioselective double addition of organic azides to octadehydrodibenzo[12]annulene derivatives with ...

Ortho-Phosphinoarenesulfonamide-Mediated Staudinger Reduction of Aryl and Alkyl Azides

Molecules, 2022
Conventional Staudinger reductions of organic azides are sluggish with aryl or bulky aliphatic azides. In addition, Staudinger reduction usually requires a large excess of water to promote the decomposition of the aza-ylide intermediate into phosphine ...
