For instance, Qiao et al. successfully functionalized PEG using alkyne end-groups and CD rings with reactive azide groups to facilitate both covalent (alkyne/azide click chemistry) and non ...

However, conventional synthesis methods for azide compounds have severe limitations. To this end, a team of researchers has developed an efficient method to prepare chemical intermediates having ...

PEG itself is protic and can lead to the formation of hydrazoic acid. It is also possible that unreacted azide salts that had settled to the bottom of the still were overheated to detonation when ...
