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.

Chemistry – A European Journal, EarlyView.The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

Chemistry – A European Journal, EarlyView.Hydrogen‐release processes in silicon chemistry occur across a broad spectrum of systems, including crystalline silicon surfaces, nanoporous materials, Zintl phases, and molecular hydrides. This Review highlights how Si─H activation and H2 evolution are governed by structure, coordination environment, and dynamic access to reactive geometries, with ...

Reversible Assembly and Disassembly of σ‐Aromatic B3 Rings
Chemistry – A European Journal, EarlyView.B3 rings are the smallest σ‐aromatic boron compounds. Here, we show for the first time that cationic diboranes with an electron‐precise (2c,2e) bond can be reversibly converted to σ‐aromatic B3 rings with electron‐deficient (3c,2e) bonding. Base‐induced disassembly of the B3 ring leads back to cationic diboranes and monoborane adducts.
