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 ...
