What are Some Examples of Pyridine-Based Catalysts?
Several pyridine-based catalysts have been developed for various applications. For example, pyridylphosphines are ligands that combine the reactivity of phosphines with the coordinating ability of pyridines. These ligands are used in palladium-catalyzed cross-coupling reactions. Another example is the use of pyridinium salts in organocatalysis, where they facilitate reactions through ionic interactions.
