Description

Application

Cationic 4-coordinate catalyst is considered “pre-activated” because no ligand dissociation is required for formation of the active catalytic species. Has reactivity profile similar to Grubbs Catalyst^® 1^st Generation but is active at much lower temperatures (below 0 °C).
