Redox Properties of Catalytically Generated Iminium Ions From α,β‐Unsaturated Aldehydes and Chiral Secondary Amines

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
We present a rapid, operationally simple, and broadly applicable protocol for the catalytic formation and in situ electrochemical characterization of chiral a,b‐unsaturated iminium ions by cyclic voltammetry (CV). Using only 5 mol% of the aminocatalyst, we systematically measure the reduction potential of over 50 iminium intermediates, revealing how ...

Masked Silylenes: Controlled Generation and Reactivity Under Thermal and Equilibrium Conditions

European Journal of Inorganic Chemistry, Volume 29, Issue 18, 22 June 2026.
This Review provides an overview of masked silylenes as bench‐stable precursors that release silylenes (R2Si:) under thermal activation or reversible equilibria. Precursor preparation, generation pathways, and characteristic reactivity are summarized, including trapping chemistry, reversible interconversions, insertion‐type processes, and small ...

Emerging Trends in Organic Photoreactions Utilizing Disulfides

European 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 ...
