An Electron‐Poor Nickel Diphosphine Complex: Synthesis, Structure, and Reactivity of Ni(dFppe)2

Chemistry – A European Journal, EarlyView.
Fluorinated diphosphine ligands such as 1,2‐bis[bis(pentafluorophenyl)phosphino]ethane (dFppe) offer powerful electronic tunability and unusual reactivity. Despite known analogues of the heavier congeners Pd and Pt, Ni complexes of dFppe remain conspicuously absent.

Cationic Sulfonium‐Based Tripodal Ligand and Its Rh(I) Complexes

Chemistry – A European Journal, EarlyView.
We report a cationic EP3‐type tripodal ligand based on an aromatic sulfonium cation (E = S+) along with a series of its Rh(I) complexes. Structural, spectroscopic, electrochemical, and computational analyses of these complexes compared to isostructural analogs (E = Si− or P) reveal pronounced electron density depletion at Rh in the sulfonium congener ...

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.

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.
