Electrochemical Intramolecular Aminobromination of Alkenes

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 2, January 16, 2026.
A versatile electrochemical method for the intramolecular aminobromination of alkenes has been developed. The method provides access to five‐, six‐, and seven‐membered heterocycles by exploiting tetrabutylammonium bromide as an electrolyte and bromine source.

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

open access: yesJournal 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

open access: yesChemistry – 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.
