The Joy of Pests: Camaraderie, Wonder and Dialectical Autonomy in UK Professional Pest Management

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
Short Abstract Using interviews and participant observation, this research explores the everyday practices and experiences of UK‐based pest management professionals. It reveals an unexpected and unalienated ‘joy of pests’ anchored in problem‐solving variety, camaraderie and zoological curiosity.

Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides

open access: yesAngewandte Chemie, Volume 138, Issue 22, 25 May 2026.
A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.

Metal‐Free and Solvent‐Free CO2 Fixation Into Cyclic Carbonates Catalyzed by a Deferiprone‐Derived Bifunctional System

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 20, 27 May 2026.
A simple bifunctional organocatalyst derived from the FDA‐approved chelator deferiprone efficiently promotes CO2 fixation into cyclic carbonates. By combining epoxide activation and nucleophilic ring opening in a single scaffold, quantitative conversions are achieved under mild, metal‐free conditions. High activity, broad substrate scope, and excellent

Porous Phenazine‐bridged Tetraoxa[8]Circulenes for Selective Gold Recovery and Heterogeneous Catalysis

open access: yesAngewandte Chemie, Volume 138, Issue 22, 25 May 2026.
Gold recycling from electronic waste using porous materials is an emerging concept to reduce the environmental impact of gold mining. In this work, we report the synthesis of a highly porous phenazine‐derived tetraoxa[8]circulene polymer and its utilization in gold capture and heterogeneous catalysis.

Unlocking the Functionalization and Reactivity of Ethylene Bridges in [2.2]Paracyclophanes: Strategies and Challenges

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 20, 27 May 2026.
Bridging the gap. Beyond deck functionalization, the ethylene bridges of [2.2]paracyclophanes offer a largely unexploited reactivity landscape. This review showcases strategies to functionalize these bridges and leverage them to build novel cyclophane architectures.
