Cymantrene–Triazole "Click" Products: Structural Characterization and Electrochemical Properties [PDF]

open access: yes, 2014
We report the first known examples of triazole-derivatized cymantrene complexes (η5-[4-substituted triazol-1-yl]cyclopentadienyl)tricarbonylmanganese(I), obtained via a “click” chemical synthesis, bearing a phenyl, 3-aminophenyl, or 4-aminophenyl moiety ...

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

open access: yesChemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

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.
