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.

Self‐Complementary Dimers Based on Zwitterionic Halogen Bond Donors

Chemistry – A European Journal, EarlyView.
In this study we present the first isolated zwitterionic homodimers based on halogen bonding (XB). After optimization of the structures by changing the Lewis base (LB) and the backbone, their dimerization was observed in gas phase, as well as, in solid state.

Dinuclear Copper(I) Complexes Featuring Metal–Metal Interactions and a μ2‐Bridging Phosphane With Additional Olefinic Binding Sites

Chemistry – A European Journal, EarlyView.
A Cu2P triangle captured in a tetrapodal phosphane tris(olefin) ligand, where all binding forces are weak apart from the Cu─P interaction. ABSTRACT The molecule Ptrop3 contains in each trop unit (trop = dibenzo[a,d]cyclohepten‐5‐yl) a rigid central seven‐membered ring with an olefinic binding site making Ptrop3 potentially a tetradentate ligand ...

Trigonal Phosphine Umpolung: Electrophilicity Driven by a Redox‐Active Boron Cluster

Chemistry – A European Journal, EarlyView.
Coupling of a phosphine to a redox‐active cluster enables polarity reversal, or umpolung, at phosphorus. Phosphines are classically known for their nucleophilicity, and while electrophilic reactivity has been observed in geometrically constrained, non‐trigonal systems, similar behavior in ordinary trigonal phosphines is rare.

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 ...
