The Intricate Sabatier Optimality of Anion Electroreduction and Its Consequences for Nitrate Reduction

open access: yesAngewandte Chemie, EarlyView.
The Sabatier principle and volcano plots declare that optimal electrocatalysis is found in the middle between strong and weak binding of key intermediates. However, it is shown here that during anion electroreduction, strong and weak binding are potential‐dependent concepts and volcanoes are mobile.

O‐Terphenyl‐basierte Familie konjugierter Makrozyklen: Selektive Erkennung von Phenylalanin im Wasser und Interaktion mit Insulin

open access: yesAngewandte Chemie, EarlyView.
Diese Studie beschreibt die Herstellung und Eigenschaften einer neuen Familie von o‐Terphenyl‐basierten Makrozyklen, TP[n] (n = 2‐8). Der Trimer bindet Phenylalanin in Wasser sehr effizient und ist dabei zehnmal selektiver als bei anderen Aminosäuren und aromatischen Neurotransmittern.

Hydrogen Isotope Exchange in Pyridine Catalyzed by an Iron(II) Imido Complex: Counterion‐Directed Regioselectivity

open access: yesAngewandte Chemie, EarlyView.
Anionic high‐spin iron(II) imido complexes are catalysts for the hydrogen isotope exchange (HIE) reaction with pyridine as the substrate. The alkali metal counter‐cation plays critical roles in activating the substrate and facilitating deuteration. These complexes catalyze site‐selective α‐, α,β,γ‐, and β,γ‐deuteration of pyridine, where the counter ...

From [NHC─H]• to Persistent σ‐Complex Radicals: Photoinduced Radical Chemistry of Imidazolium Salts

open access: yesAngewandte Chemie, EarlyView.
Visible‐light excitation of electron donor–acceptor (EDA) complexes between imidazolium salts and triarylamines enables controlled single‐electron transfer (SET) and reveals a family of carbene‐centered σ‐complex radical cations. Cryogenic electron paramagnetic resonance (EPR) captures the elusive [NHC─H]• intermediate and its thermal evolution into ...

Slowing Down Water: Enhanced and Cation‐responsive MRI Contrast

open access: yesAngewandte Chemie, EarlyView.
The controlled modification of mesoporous silica nanoparticle side walls with kosmotropic motifs supports an ability to reduce water diffusive mobility and dramatically increase MRI contrast to levels unprecedented for highly kinetically stable Gd‐DOTA configurations (both q = 1 and q = 0).
