Structural Dependence of Catenand Effect: Thermodynamic and Kinetic Modulation of Catenane Coordination Properties via Ring‐size and Exocyclic Substituent Variation

open access: yesAngewandte Chemie, EarlyView.
By modifying ring size and exocyclic substituents, effects of ligand interlocking on metal coordination features is explored. Through systematic analysis of CuI catenanes, relationship between structural parameters of the interlocked ligands and coordination properties like geometry, stability, and reactivity is established.

Electrochemical ⍺‐C─H Functionalization of Nitramines for Accessing Bifunctional Energetic Heterocycles

open access: yesAngewandte Chemie, EarlyView.
An electrochemical α‐C─H functionalization of nitramines enables the synthesis of molecules containing bifunctional energetic heterocycles with promising properties. A telescoped, HNO3‐free sequence involving nitration and azolation steps offers a safer, modular, and scalable platform for the synthesis of energetic compounds.
