title: Role of grafted alkoxybenzylidene ligand in silica-supported Hoveyda-Grubbs-type catalysts.
abstract: Using both circulating flow and batch reaction systems, we explored the role of immobilized alkoxybenzylidene ligands in capturing and stabilizing active ruthenium species. The bidentate ligands turned out to considerably affect reaction rate, catalyst decomposition, leaching and recycling. It was also observed that the dynamic release-return catalytic pathway worked more efficiently in a batch system leading to less catalyst decomposition and leaching.
