Abstract

Abstract : 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 α‐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. Abstract : 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. The heterobimetallic Ir III /Pd II complex appears as active precatalyst in tandem catalytic transformations of 4‐bromoabenzaldehyde to 4‐biphenylmethanol derivatives.
