Are N-Heterocyclic Carbene Radical Cations Relevant Intermediates in Radical Transformations? Open
N-Heterocyclic carbenes (NHC) radical cations have been increasingly hypothesized as key intermediates in NHC-promoted radical reactions, but have eluded direct observation so far. Herein, we report joint experimental and theoretical effor…

Incommensurate and commensurate antiferromagnetic orders in the kagome compound Open
We report on the synthesis of single crystals of the kagome compound, UV$_6$Sn$_6$, and present the results of magnetization, electrical resistivity, heat capacity, x-ray, and neutron diffraction experiments to characterize the structure a…

Merging cyclopentadienone tuning and CO to isonitrile substitution to develop photo-activated iron cyclopentadienone catalysts Open
The properties of new iron cyclopentadienone complexes for borrowing hydrogen reactions have been determined through optimal tuning of both the cyclopentadienone scaffold and the isocyanide ligand.

Biomimetic Pseudopeptides to Decipher the Interplay between Cu and Methionine‐Rich Domains in Proteins Open
Maintaining tightly copper homeostasis is crucial for the survival of all living organisms, in particular microorganisms like bacteria. They have evolved a number of proteins to capture, transport and deliver Cu(I), while avoiding Fenton‐l…

Outstanding Superoxide Dismutase Catalytic Activity Of Simple Peptide‐Based Nickel(II) Complexes Open
We present here the most active synthetic Ni superoxide dismutase (NiSOD) mimic reported to date. Reactive oxygen species are aggressive compounds, which concentrations are tightly regulated in vivo. Among them, the superoxide anion, O 2 ⋅…

Improved Protocols for the Synthesis of Precursors of Thiazol-2-ylidene N-Heterocyclic Carbenes Open
We report improved protocols for the synthesis of thiazolium precatalysts from primary amines, carbon disulfide, and α-halo ketones. For N-alkyl-substituted derivatives, yields of the corresponding thiazolethiones can be dramatically impro…

Boosting N-Heterocyclic Carbene Radical Organocatalysis with Nickel Chemistry: A Rational Mechanistic Study-based Approach. Open
A cooperative NHC/nickel catalytic methodology has been developed for the synthesis of ketones employing aromatic aldehydes and tertiary alkyl iodides. All key steps of the postulated catalytic cycle were validated with comprehensive stoic…
