Gallium‐Catalyzed Tandem Carbonyl–Olefin Metathesis/Dehydrogenative Coupling Enables Rapid Access to Cyclopentenes

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
A cationic gallium(III) catalyst enables rapid construction of substituted cyclopentenes via tandem carbonyl‐ene metathesis/Friedel–Crafts coupling. Electronic tuning of alcohol electrophiles allows access to diverse, densely functionalized rings in a single operation.

Emerging Trends in Organic Photoreactions Utilizing Disulfides

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...
