Homoleptic and Heteroleptic Borylones L1‐B(Ph)‐L2

Angewandte Chemie, EarlyView.
Density functional theory and CCSD(T) calculations reveal that homoleptic and heteroleptic borylones L1–B(Ph)–L2 are thermodynamically accessible. Remarkably, the homoleptic borylones B(Ph)(N2)2 and B(Ph)(SPh2)2 exhibit higher bond dissociation energies than the related carbones.

Isolation and Reactivity of a Square‐Planar Trisamido Silane

Angewandte Chemie International Edition, EarlyView.
We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...

Two‐Dimensional Polymers as Modular Metal‐Free Solid‐State Catalysts for Efficient Sono‐Piezo‐Photocatalytic Hydrogen Peroxide Production

Angewandte Chemie International Edition, EarlyView.
This study demonstrates the high piezo‐photocatalytic activity of solid molecular catalysts (SMCs) in the production of hydrogen peroxide from water and oxygen. Through the rational design of molecular motifs (diphenylpyridine or terpyridine) and backbone functionalities (methyl group, aliphatic amine antenna, or aromatic pyrrole unit), as well as ...
