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.

Gold(I) Phosphine/Phosphido‐Borohydride Complexes

European Journal of Inorganic Chemistry, EarlyView.
Synthesis, structure, and electrochemical characteristics of a homologous series of gold(I) complexes featuring phosphine and phosphido–borohydride ligands. A homologous series of linear, mononuclear gold(I) phosphine/phosphido‐borohydride complexes, encompassing [Au(PR3)2]+ 1, [Au(PR3)(PR2BH3)] 2 and [Au(PR2BH3)2]– 3 (R = tBu, Ad), has been prepared ...

Expanded Scorpionate and Siderophore‐Inspired Ligands: From Foundational Designs to Modern Applications

European Journal of Inorganic Chemistry, EarlyView.
The concept of scorpionate ligands has evolved significantly since the introduction of tris(pyrazolyl)borate. By integrating a biological supramolecular ligand scaffold with the classic scorpionate architecture, researchers have made notable strides in mimicking the active sites of nitrogenase and advancing homogeneous catalysis.
