The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain
Chemistry – 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 ...

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates
Chemistry – A European Journal, EarlyView.ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Synthesis and Reactivity of 3‐Aminosydnones in Cycloaddition Reactions With Alkynes
Chemistry – A European Journal, EarlyView.The synthesis, functionalization, and reactivity as dipoles of 3‐aminosydnones have been investigated. These neglected compounds undergo smooth cycloaddition reactions with strained alkynes, leading to 1‐aminopyrazoles. ABSTRACT We present in this article the synthesis, functionalization, and properties of 3‐aminosydnones, a forgotten class of ...
