Palladium catalyst is a precious metal catalyst made of palladium as the main active component. It is a kind of catalyst often used in chemical and chemical reaction processes. Changes and improvements, compound with other metal or co-catalyst active components to optimize performance.
Application of palladium catalyst:
1. Pd-catalyzed coupling reaction.
The use of palladium to catalyze the coupling reaction can solve the problems caused by the traditional homogeneous catalytic system, such as the difficulty of separation of reaction products and the inability to reuse the catalyst, and has a very good application. The most representative palladium-catalyzed coupling reactions are the Heck reaction and the Suzuki coupling reaction.
2. Pd-catalyzed cycloaddition reaction.
The [4+2] cycloaddition reaction catalyzed by palladium complexes has the remarkable characteristics of less catalyst dosage, high yield, good selectivity and mild reaction conditions, and has become a hot research topic in the [4+2] cycloaddition reaction. . The [4+2] cycloaddition reaction catalyzed by palladium chiral Lewis acid has made a breakthrough in research.
3. Pd-catalyzed reaction of diazonium compounds.
The decomposition and subsequent reactions of diazonium compounds under the action of transition metal catalysts have been widely used in organic synthesis.
