Emerging Trends in Organic Photoreactions Utilizing Disulfides

European Journal of Organic Chemistry, EarlyView.
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 ...

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

European Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

1,2‐Diazetidines − Structure, Synthesis, and Functionalization

European Journal of Organic Chemistry, EarlyView.
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.
