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

1,2,6‐Thiadiazin‐4‐ones: Robust Photocatalysts for the Green Aerobic Oxidation of Sulfides to Sulfoxides

European Journal of Organic Chemistry, EarlyView.
A new photocatalyst for the aerobic photochemical oxidation of sulfides to sulfoxides is described under really low catalyst loading (0.01 mol%) and methanol as the green solvent. The chemoselective oxidation of sulfides to sulfoxides is accomplished using a new family of photocatalysts, namely 1,2,6‐thiadiazin‐4‐ones. Utilizing a low catalyst loading (

Porcine Liver Esterase‐Catalyzed Dynamic Kinetic Resolution of a Lactone‐Bridged Biaryl: Impact of Organic Cosolvents on Enantioselectivity

European Journal of Organic Chemistry, EarlyView.
A stereolabile lactone‐bridged biaryl enables dynamic kinetic resolution to provide a conformationally stable ring‐opened biaryl. A significant positive effect of water‐immiscible organic cosolvents on the enantioselectivity in a reaction catalyzed by porcine liver esterase has been discovered for the first time.

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

European Journal of Organic Chemistry, EarlyView.
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.
