Regio‐ and Diastereoselective C–C Silylation of Cyclopropyl Acetates Harnessing Fluorinated Poly(pyridyl)Borate Rhodium Catalysts

open access: yesChemistry – A European Journal, EarlyView.
Fluorinated poly(pyridyl)borates have been utilized to stabilize rhodium‐diene complexes and as supporting ligands in rhodium‐catalyzed redox‐neutral C–C silylation of cyclopropyl acetates, producing silicon‐containing heterocyclic products, dioxasilolanes.

Emissive Liquid Crystalline Boron C,N‐Chelates: Synthesis, Self‐assembly, and Photophysical Properties

open access: yesChemistry – A European Journal, EarlyView.
Novel emissive liquid crystalline boron C,N‐chelates were prepared by integrating mesogenic units into the boron C,N‐core. Depending on the substituent at the boron, stable SmA or N mesophases were achieved while maintaining intense blue emission with excellent quantum yields (61%–100%).

Ion–Molecule Reaction Products as Probes and Precursors for Preparative Mass Spectrometry

open access: yesChemistry – A European Journal, EarlyView.
Ion–molecule reactions in the gas phase of mass spectrometers are important for preparative mass spectrometry because they (1) provide knowledge about the intrinsic reactivity of ions, helping to predict and control their reactivity at interfaces, and (2) generate new complex ions that can be mass selected and deposited on surfaces.

Addition Reactions of Phosphorus‐Centered Radicals onto Olefins: Interplay Between Stability and Reactivity

open access: yesChemistry – A European Journal, EarlyView.
The energetics of the addition reaction of P‐centered radicals onto alkenes are primarily ruled by the stability of the attacking radical, as outlined by the computational screening of a wide range of reactions. In addition, donor‐acceptor substituents at the olefin have an important tuning role.
