A Hoveyda–Grubbs‐Type Olefin Metathesis Catalyst Bearing a Fluorinated Unsymmetrical NHC Ligand

European Journal of Inorganic Chemistry, EarlyView.
A fluorinated unsymmetrical NHC ruthenium complex was synthesised and employed as a catalyst for olefin metathesis reactions. The modification of the steric and electronic properties of the NHC ligand through the introduction of fluorine substituents results in improved activity but lower selectivity compared to the analogous non‐fluorinated NHC ...

Properties of [Fe(salen)]2‐μ‐Oxo Derivatives and Their Effect on Catalytic Hydrophosphination

European Journal of Organic Chemistry, EarlyView.
A series of [Fe(salen)]2‐μ‐oxo and [Fe(salophen)]2‐μ‐oxo complexes were synthesized to probe how ligand electronics and backbone rigidity influence redox behavior and catalytic hydrophosphination of styrene. Electron‐withdrawing substituents enhance stability and activity, enabling tunable, efficient C–P bond formation.

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.
