Nitrogen‐Rich, Tröger's Base‐Linked Porous Organic Polymers (POPs) as Heterogeneous Catalysts and Adsorbents of Organic Pollutants From Water

Journal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
Synthesized Tröger's based POPs showed great versatility in heterogeneous catalysis reactions and for pollutant adsorption. ABSTRACT Porous organic polymers are a new class of polymeric materials that combine permanent porosity, high surface area, monomer diversity, and synthetic tunability, making them highly promising candidates for application in ...

Highly Efficient Organocatalytic House‐Meinwald Rearrangement for the Facile Synthesis of Aldehydes: Swift Access to Ibuprofen

Chemistry – A European Journal, Volume 32, Issue 2, 9 January 2026.
We use readily available epoxides and 0.5 mol% bis(trifluoromethane)sulfonimide (Tf2N) as a catalyst to synthesize a broad range of aldehydes in yields ranging from 89% to 97%. Furthermore, we identified aldehyde dimerization intermediates at lower temperatures and observed their cleavage at 55 °C.

Synthesis of Functionalized Homoallylic Alcohols via a Salt‐Free Three‐Component Nickel‐Catalyzed Coupling Reaction

Advanced Synthesis &Catalysis, Volume 368, Issue 2, January 2026.
A nickel catalyzed three‐component coupling reaction between an aldehyde, a secondary amine, and butadiene allows a straightforward access to 5‐aminopent‐3‐en‐1‐ol scaffolds according to a salt‐free process. Key steps are oxidative coupling reaction between one aldehyde, one butadiene on a low valent nickel precursor, and the nucleophilic attack of a ...

The Chemistry of Subphthalocyanines: Synthetic Strategies for their Axial, Peripheral, and Remote Postfunctionalization

ChemistryEurope, Volume 4, Issue 1, January 2026.
From axial and peripheral reactivity to remote derivatization, the chemical versatility of subphthalocyanines (SubPcs) renders them ideal scaffolds for the design of advanced functional materials. This review assembles the synthetic toolbox, key reaction conditions, and future challenges in SubPc functionalization, guiding the development of next ...

Imidazoline‐Proline and Imidazoline‐Prolinate Ligands for Copper‐Catalyzed Asymmetric Exo‐Selective [3 + 2] Cycloaddition of Iminoesters with Nitroalkenes

ChemistryEurope, Volume 4, Issue 1, January 2026.
From a modular synthesis of nonphosphine chiral nitrogen‐based chiral imidazoline–amino acid ligands, two new chiral imidazoline–proline‐copper catalysts are developed for targeting exo‐selective [3 + 2] cycloaddition reaction. Density functional theory studies rationalize the observed stereoselectivity and the distinct chiral pockets of the two ...
