precatalytic
Precatalytic is an adjective used to describe catalysts that are not active in their initial form but are converted, under reaction conditions, into the active catalytic species. In many catalytic cycles the active metal center is generated from such precursors through a defined activation step, which may involve changes in oxidation state, ligand loss, or other chemical transformations that reveal or create the true catalytic site.
Activation of precatalysts occurs in situ and depends on the reaction environment, including temperature, solvent, and
Advantages of using precatalysts include improved air and moisture stability, easier handling and storage, and more
Applications of precatalytic systems are widespread in modern catalysis, particularly in palladium- and ruthenium-catalyzed processes. Precatalysts
