Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

Chemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Turning Bonding Into Function: The Emerging Role of the Bioactive Selenium─Metal Motif in Toxicology and Medicinal Chemistry

Chemistry – A European Journal, EarlyView.
Balancing Act: Se─M bond serving as the fulcrum of the balance scale to compare the different weight of toxicity and therapeutic effects in biological environment. ABSTRACT The synthesis and characterization of organo‐selenium compounds have attracted considerable interest for decades, driven by the search for efficient catalysts and bioinspired ...

Designing a Triplet 2‐Formylphenylnitrene With Fast Tunneling Reactivity

Chemistry – A European Journal, EarlyView.
A 3‐CF3 substituent accelerates tunneling in triplet 2‐formylphenylnitrene, making its reactivity in cryogenic matrices too fast for conventional IR spectroscopic detection. Bringing this chemistry to low‐temperature solutions allows suppression of intrinsic nitrene dimerization through faster cyclization, which even outcompetes the 1,4‐H shift ...
