• Loss and Reformation of Ruthenium Alkylidene: Connecting Olefin Metathesis, Catalyst Deactivation, Regeneration, and Isomerization 

      Engel, Julien; Smit, Wietse; Foscato, Marco; Occhipinti, Giovanni; Törnroos, Karl Wilhelm; Jensen, Vidar Remi (Peer reviewed; Journal article, 2017)
      Ruthenium-based olefin metathesis catalysts are used in laboratory-scale organic synthesis across chemistry, largely thanks to their ease of handling and functional group tolerance. In spite of this robustness, these ...
    • Phosphine-Based Z‑Selective Ruthenium Olefin Metathesis Catalysts 

      Smit, Wietse; Koudriavtsev, Vitali; Occhipinti, Giovanni; Törnroos, Karl Wilhelm; Jensen, Vidar Remi (Peer reviewed; Journal article, 2016-05-18)
      Whereas a number of highly Z-selective ruthenium-based olefin metathesis catalysts bearing N-heterocyclic carbene ligands have been reported in recent years, Zselectivity has so far been difficult to achieve for phosphinebased ...
    • Pyridine-Stabilized Fast-Initiating Ruthenium Monothiolate Catalysts for Z-Selective Olefin Metathesis 

      Occhipinti, Giovanni; Törnroos, Karl Wilhelm; Jensen, Vidar Remi (Peer reviewed; Journal article, 2017)
      Pyridine as a stabilizing donor ligand drastically improves the performance of ruthenium monothiolate catalysts for olefin metathesis in comparison with previous versions based on a stabilizing benzylidene ether ligand. ...
    • Silica-supported Z-selective Ru olefin metathesis catalysts 

      Renom-Carrasco, Marc; Mania, Philipp; Sayah, Reine; Veyre, Laurent; Occhipinti, Giovanni; Jensen, Vidar Remi; Thieuleux, Chloé (Peer reviewed; Journal article, 2020)
      Recently reported thiolate-coordinated ruthenium alkylidene complexes show promise in Z-selective and stereoretentive olefin metathesis reactions. Herein we describe the immobilization of three Ru complexes containing a ...
