Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water

European Journal of Organic Chemistry, EarlyView.
The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.

Confinement Effects on the RhIIICp* / Polyoxometalate System in Photochemical CO2 Reduction Reactions: Porous Organic Polymer Versus Metal–Organic Framework

ChemCatChem, Volume 18, Issue 5, 13 March 2026.
Confining of the same catalytic polyoxometalate (POM) – pentamethylcyclopentadienyl rhodium (RhIIICp*) system in either MOF or POP causes a change in POM's role from electron reservoir to proton relay in photochemical CO2 reduction reaction. The detailed structure of the heterogenized POM‐RhIIICp* system is established by dedicated NMR techniques and ...

Olefin Polymerizations Oriented by Rational Designs of Group‐13 Compounds

The Chemical Record, Volume 26, Issue 3, March 2026.
In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...

Observation of Near‐Infrared Photothermal and Photoacoustic Effects in a Metallosupramolecular Trefoil Knot

Angewandte Chemie, Volume 137, Issue 48, November 24, 2025.
A metallosupramolecular trifold knot has been prepared from three bisimidazole ligands and three dinuclear half‐sandwich metal complexes. The topology of the trifold knot enforces strong π⋅⋅⋅π interactions between the building blocks, which results in near‐infrared (NIR) light absorption.
