2,3‐Diboratabutadiene Complexes of Group 4 Metals and their Donor‐Induced Oxidative Cleavage to Methyleneboranes Open

Philipp Grewelinger, Carsten Präsang, Bernd Morgenstern, David Scheschkewitz · 2025

Metal complexes of conjugated olefins have been known for a century. The formal heterosubstitution of carbon atoms in such ligands significantly alters their electronic properties. While several examples with terminal boron centers are kno…

π‐Complexes Derived from Non‐classical Diboriranes: Side‐on vs. End‐on Carbonylative Ring Expansion Open

Philipp Grewelinger, Carsten Präsang, Michael Zimmer, Bernd Morgenstern, David Scheschkewitz · 2024

Unlike cyclopropanes, the analogous B 2 C species (diboriranes) tend to adopt non‐classical Hückel‐aromatic structures with bridging moieties R between the boron atoms. The coordination of the thus generated cyclic 2e − π‐system to transit…

π‐Komplexe aus Nicht‐Klassischen Diboriranen: Side‐on vs. End‐on Carbonylierende Ringerweiterung Open

Philipp Grewelinger, Carsten Präsang, Michael Zimmer, Bernd Morgenstern, David Scheschkewitz · 2024

Im Gegensatz zu Cyclopropanen neigen die analogen B 2 C‐Spezies (Diborirane) dazu, nicht‐klassische Hückel‐aromatische Strukturen mit verbrückenden Resten R zwischen den Boratomen auszubilden. Die Koordination des so erzeugten zyklischen 2…

Diboriranide σ‐Complexes of d‐ and p‐Block Metals Open

Philipp Grewelinger, Tim Wiesmeier, Carsten Präsang, Bernd Morgenstern, David Scheschkewitz · 2023

Diboriranides are the smallest conceivable monoanionic aromatic cycles, yet only limited examples have been reported and their reactivity and complexation behavior remain completely unexplored. We report a straightforward synthesis of the …

Halogen‐Bonded Liquid Crystals Open

Carsten Präsang, Duncan W. Bruce · 2023

While the halogen bond has been recognised and studied for over a hundred years, it is only in more recent times that chemists have begun to apply it and see its possibilities as another supramolecular interaction that can be deployed in t…
