Integrated “all-in-one” strategy to construct highly efficient Pd catalyst for CO2 transformation

The designed AIO catalyst, uniquely featuring co-coordination with AcGlu and bis(benzimidazolium) units at the Pd center. The structure promotes the formation of NHC-CO 2 and AcGlu-CO 2 with a TOF of 3456 h −1 in reaction of CO 2 and propargylic amine.
