Cleavage of macromolecular RAFT chain transfer agents by sodium azide during characterization by aqueous GPC [PDF]

open access: yes, 2017
Accurate and reliable analysis of polymers by GPC is vital in the field of controlled radical polymerisation. Often, water-soluble polymers are analysed by aqueous gel permeation chromatography (GPC) in a solvent containing dilute sodium azide as an anti-

Taming tosyl azide: the development of a scalable continuous diazo transfer process [PDF]

open access: yes, 2016
Heat and shock sensitive tosyl azide was generated and used on demand in a telescoped diazo transfer process. Small quantities of tosyl azide were accessed in a one pot batch procedure using shelf stable, readily available reagents. For large scale diazo

Modular synthesis of mono, di, and tri-1,4-disubstituted-1,2,3-triazoles through copper-mediated alkyne–azide cycloaddition [PDF]

open access: yes, 2011
The synthesis of 1,2,3-triazoles was developed employing sequential copper azide–alkyne cycloaddition, tosylation, sodium azide, and copper azide–alkyne steps. This approach allowed the synthesis of two and three 1,2,3-triazole rings. A preliminary study
