Homo- and Heterobimetallic Complexes Bearing NHC Ligands: Applications in -Arylation of Amide, Suzuki-Miyaura Coupling Reactions, and Tandem Catalysis

A heterobimetallic Ir-III/Pd-II complex from a dicarbene donor ligand featuring cyclometalated Ir-III and PEPPSI type Pd-II is presented along with a homodinuclear PEPPSI type Pd-II complex starting from the same bis-imidazolium salt. All the Pd-II complexes are active precatalyst in both -arylation...

More Information
Summary:A heterobimetallic Ir-III/Pd-II complex from a dicarbene donor ligand featuring cyclometalated Ir-III and PEPPSI type Pd-II is presented along with a homodinuclear PEPPSI type Pd-II complex starting from the same bis-imidazolium salt. All the Pd-II complexes are active precatalyst in both -arylation and Suzuki-Miyaura coupling reactions. The heterobimetallic Ir-III/Pd-II complex shows much higher yields in tandem C-C coupling/transfer hydrogenation reactions compared to the equimolar mixture of their mononuclear Pd-II and Ir-III counterparts.
