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 ...

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

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 ...

Kinetic resolution of cyclic benzylic azides enabled by site- and enantioselective C(sp3)–H oxidation

Nature Communications, 2022
Catalytic kinetic resolution of racemates is among the best ways to prepare enantiopure compounds, but this process is difficult with organic azides given the small size of the azido group.
