Well‐Defined Anilido–Imine Iron(II) Complexes for Catalytic Intramolecular Alkene Hydroamination of Primary Amines

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
We synthesize and characterize a series of well‐defined anilido–imine Fe(II) alkyl complexes that demonstrate high activity and selectivity in the cyclohydroamination of unprotected primary amines tethered to unactivated alkenes. By tuning the steric and electronic parameters of the anilido–imine ligand, we develop a catalyst that outperforms ...

Pyridyl‐Imidazopyridine Derivatives Displaying Submicromolar Activity Against Trypanosoma cruzi

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
Previously reported pyridyl‐thiazoles and highly active imidazopyridines against Trypanosoma cruzi inspired the design of a new series of pyridyl‐substituted imidazopyridines. Among the synthesized compounds, 5h emerged as the most promising derivative, displaying potent trypanocidal activity (EC50 = 0.16 μM), excellent selectivity (SI > 1250), and ...

Beyond Single‐Active Sites: The Emergence of High‐Entropy Perovskites in Energy and Environment Catalysis

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
This review examines high‐entropy perovskites (HEPs) as a promising catalyst platform for energy and environmental applications. The focus is on configurational entropy engineering, design and synthesis, and computational understanding. These materials possess tunable active sites, enhanced stability, and improved electronic interactions, leading to ...
