Photolytic Hydrophosphination: Insights Into Catalyzed and Uncatalyzed Processes

Chemistry – A European Journal, EarlyView.
Catalyst‐free photolytic hydrophosphination is demonstrated for vinyl arenes and activated alkenes in polar protic (alcohol) solvents. These reactions appear to be closed‐shell, affirming that even ambient light can impact a reaction—a potentially broad influence on even mundane reactions.

Flipping the Card With Enantiodivergent Organocatalysis

Chemistry – A European Journal, EarlyView.
This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Impact of Electronic Substitution and Planarization on the Photophysical Properties of 2‐(2′‐Hydroxyphenyl)benzoxazole or 2‐(2′‐Hydroxyphenyl)‐Dimethylindole

European Journal of Organic Chemistry, EarlyView.
We report the synthesis, structural characterization, and photophysical investigation of a series of Excited‐State Intramolecular Proton Transfer‐active HBO and HDMI derivatives. By varying heterocyclic cores, substituents, and ethynyl planarization, we establish structure–property relationships governing fluorescence behavior.
