2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

ChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Large‐Area Metallic Nanohelices for Engineering Optical Chirality

Small, EarlyView.
By exploiting the nanoscale engineering of residual stresses in metallic thin films, this method enables scalable fabrication of submicrometer metallic helices with tunable geometry and material versatility. The resulting structures exhibit pronounced chiroptical responses across the mid‐ to near‐infrared range, offering a robust platform for chiral ...
