Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst
Chemistry – A European Journal, EarlyView.While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Decoding Heptazine Architectures: From Molecular Association to Structural Insight
Chemistry – A European Journal, EarlyView.A comprehensive study (NMR and theoretical) of three novel heptazine derivatives that self‐assemble into dimers has been conducted, highlighting their versatility as a platform for multifunctional supramolecular and optoelectronic materials. ABSTRACT Heptazine (Hpz) derivatives display remarkable supramolecular organization governed by noncovalent ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.
