Isolable ArInH2: Double Hydroindation Agent

open access: yesChemistry – A European Journal, EarlyView.
Stable crystalline monomeric indium dihydride ArInH2 was isolated and completely characterized using effective support of the P,C,P‐pincer ligand (Ar = 2,6‐(tBu2PO)2C6H3). It serves as unparalleled hydroindation agent, thereby extending the family of known hydrometallation process relying on heavy p‐block metals.

Non‐Covalent Fluorine–Silica Anchoring of a Molecular Platinum(II) bis(NHC) Catalyst: Structure, Interface Control, and Hydrosilylation Activity

open access: yesChemistry – A European Journal, EarlyView.
A Pt(II) bis(NHC) complex is immobilized on mesoporous silica through directional F–Si interactions encoded in the ligand framework. Quantitative 19F{29Si} REDOR experiments and molecular dynamics simulations establish Å‐scale catalyst–support contacts and define the interfacial organization.

N‐Heterocyclic Carbenes and N‐Heterocycles as Synthetic Reagents and Building Blocks

open access: yesChemistry – A European Journal
AbstractN‐Heterocyclic carbenes (NHCs) have become important tools in modern synthetic chemistry due to their versatility as organocatalysts and ligands in organometallic complexes. Since their first isolation and characterization, NHCs have demonstrated significant utility in various catalytic processes, offering advantages such as strong σ‐electron ...

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.
