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

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-

One pot ‘click’ reactions: tandem enantioselective biocatalytic epoxide ring opening and [3+2] azide alkyne cycloaddition [PDF]

open access: yes, 2010
Halohydrin dehalogenase (HheC) can perform enantioselective azidolysis of aromatic epoxides to 1,2-azido alcohols which are subsequently ligated to alkynes producing chiral hydroxy triazoles in a one-pot procedure with excellent enantiomeric excess.

Continual reproduction of self-assembling oligotriazole peptide nanomaterials. [PDF]

open access: yes, 2017
Autocatalytic chemical reactions, whereby a molecule is able to catalyze its own formation from a set of precursors, mimic nature's ability to generate identical copies of relevant biomolecules, and are thought to have been crucial for the origin of life.
