Oxidation‐Deformylation Cascade Catalyzed By a Mononuclear Copper Complex

Chemistry – A European Journal, EarlyView.
A bioinspired copper complex is able to catalyze two successive oxidative steps of alcohol conversion in the presence of hydrogen peroxide under mild conditions: (i) alcohol oxidation to aldehyde and (ii) aldehyde deformylation. Isotopic effects on the reaction rates indicate that hydrogen atom abstraction is rate limiting for both steps.

Influence of Protonation and Iron(II) Complexation on Magnetic Interactions in Spin‐Labeled Mechanically Interlocked Molecules

Chemistry – A European Journal, Accepted Article.
This study reports the effects of protonation and Fe(II) complexation on the exchange coupling and magnetic properties of a [2]‐rotaxane and its corresponding free‐axle biradicals. The rotaxane features nitronyl‐nitroxide units as bulky stopper groups, a triazole‐pyridine‐triazole ligand as the axle component, and a bipyridine moiety within the ...

Fast and scalable inference for spatial extreme value models

Canadian Journal of Statistics, EarlyView.
Abstract The generalized extreme value (GEV) distribution is a popular model for analyzing and forecasting extreme weather data. To increase prediction accuracy, spatial information is often pooled via a latent Gaussian process (GP) on the GEV parameters. Inference for GEV‐GP models is typically carried out using Markov Chain Monte Carlo (MCMC) methods,

Design and Synthesis of Tetrahydropyrrolo[3,4‐c]Pyrazole Sigma‐1 Receptor Ligands

ChemMedChem, EarlyView.
This study highlights the tetrahydropyrrolo[3,4‐c]pyrazole scaffold as a promising platform for S1R ligands development. Key findings include compound 19’s high S1R affinity (Ki=75 nM), influenced by strategic nitrogen substitutions and reduced steric hindrance.
