Latest Patents

Xiangyang Wu holds a patent for an N-heterocyclic carbene type palladium catalyst and its preparation method, as well as its applications. This invention relates to a novel palladium catalyst that boasts high activity and versatility. The preparation process involves selecting glyoxal as the raw material to synthesize glyoxaldiimine in the presence of Lewis acid or Bronsted acid. This is followed by a reaction with paraformaldehyde to obtain the NHC type ligand. The palladium then reacts with compounds containing carbon-nitrogen double bonds to form a palladium cyclic dimer. The resulting palladium cyclic dimer is coordinated with the NHC type ligand to create the NHC type palladium catalyst. This catalyst demonstrates excellent reaction activity in various catalytic-coupling reactions, including Suzuki-Miyaura, Heck, Buchwald-Hartwig, Kumada-Tamao-Corriu, Sonogashira, Negishi, and α-ketone arylation reactions. Some of these reactions can even be conducted with an extremely low concentration of catalyst, showcasing its favorable industrialization prospects.
