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

open access: yesChemistry – 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.

Hydrogen Release From Silicon─Hydrogen Systems: From Surface Chemistry to Higher‐Coordinate Molecular Mechanisms

open access: yesChemistry – 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 ...

Persilylated and Related Silyl Anion‐Induced Synthesis of Group 3–10 Metal–Silyl Complexes

open access: yesChemistry – A European Journal, EarlyView.
Persilylated and related silyl anions serve as powerful tools for constructing metal–silyl complexes across group 3–10 elements. Their strong σ‐donating ability and steric bulk stabilize low‐coordinate, reactive species and enable unique bonding motifs.

Light, Redox, and Ligand Noninnocence Cooperate in Naphthalene Diimide‐Functionalized N‐Heterocyclic Carbene Iridium Complexes

open access: yesChemistry – A European Journal, EarlyView.
Naphthalene diimide–N‐heterocyclic carbene iridium complexes display uncommon multistimuli‐responsive behavior combining strong Cl(lp)···π interactions, ligand non‐innocence, visible‐light photoreduction, and conPET photocatalysis. The study also provides new insight into the interaction of NDI platforms with fluoride/basic anions, revealing unexpected

Exploring the Catalytic Activity of Ge(II) and Sn(II) Cationic Crown Ether Complexes: Hydrosilylation

open access: yesChemistry – A European Journal, EarlyView.
Easily synthesized [Ge([12]crown‐4)2][OTf]2 catalyzes the hydrosilylation of aldehydes to give reductively coupled ethers via a carbonyl‐activated reaction pathway. The mechanism proceeds through two distinct steps: hydrosilylation followed by etherification. The open coordination face of the active cationic Ge(II) catalyst facilitates the coordination

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

open access: yesChemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to
