A Fast-Initiating Ionically Tagged Ruthenium Complex: A Robust Supported Pre-catalyst for Batch-Process and Continuous-Flow Olefin Metathesis
was designed and anchored onto sulfonated silica, thereby forming a robust and highly active supported olefin‐metathesis pre‐catalyst for applications under batch and continuous‐flow conditions. The involvement of an oxazine–benzylidene ligand allowed the reactivity of the formed Ru pre‐catalyst to be efficiently controlled through both steric and electronic activation. The oxazine scaffold facilitated
