The chemistry of azides

, 1973
A review of the decomposition of alkyl and aryl azides by thermolysis and photolysis has been accomplished. Organic azides are a very distinct species that undergo its own unique reactions. Azides decompose to form an electron deficient nitrogen having a

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

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 ...

GPR124 Alleviates Blood–Brain Barrier Disruption by Enhancing Microvascular Endothelial Function after Traumatic Brain Injury

Advanced Science, EarlyView.
Our study reveals the protective role of GPR124 in maintaining BBB integrity and promoting neurological recovery following TBI. It makes a significant contribution by uncovering a novel molecular interaction between GPR124 and FGFBP1 and linking this to activation of the Wnt/β‐catenin signaling pathway in vascular repair mechanisms.

New possibilities for the synthesis of reactive functional aminopolysilanes using azide pathway [PDF]

Memoirs of the Scientific Sections of the Romanian Academy, 2014
Two new reaction frameworks with high stereospecificity and high yields are described. Azidopolysilanes offers multiple options for obtaining aminopolysilanes, either by reducing the azido group using the Staudinger technique or by Huisgen 1,3 ...
