Zinc (II) Imidoyl Azide Coordination Polymer, an Unexpected Compound with Insensitive Explosive Properties

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 20, May 28, 2025.
A new type of coordination polymer has been discovered while looking for high‐performance, insensitive secondary explosives. This polymer made of scarce imidoyl azide structures, demonstrates interesting pyrotechnic characteristics like a density greater than 2.00 g.cm−3 and great insensitivity towards thermal and mechanical stresses.

Diving into the Shielding Surfaces: Construction of Atropisomeric Axes via Multicomponent Reactions

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 18, May 23, 2025.
We successfully designed and synthesized a diverse library of atropisomeric molecular systems using a scaffold hopping strategy based on the GBB‐3CR. Structural and computational analyses revealed key CH⋅⋅⋅π and π⋅⋅⋅π interactions, aromatic shielding effects, and conformational dynamics, providing insights into their potential biological relevance ...

Recent Advances in the α‐Hydrazination (α‐Amination) of Carbonyl Compounds

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 17, May 21, 2025.
In recent years, notable progress has been achieved in the α‐hydrazination (α‐amination) of carbonyl compounds, especially in the direct asymmetric electrophilic α‐hydrazination with dialkyl azodicarboxylates. This review summarizes all the methods that appeared over the past decade, categorized based on the type of the reactive chiral intermediate ...
