1,1-Bis(diphenylphosphino)methane (dppm) was used as a linker ligand for the preparation of a series of heterobimetallic RhIII-PtII and RhIII-PdII complexes. These complexes were characterized by means of several analytical and spectroscopic methods. The catalytic activities of these heterobimetallic complexes were carried out in three different tandem reactions: Namely, transfer hydrogenation (TH)/dehalogenation (DH), TH/Suzuki-Miyaura coupling, and coupling of benzylic alcohols with nitrobenzenes for Schiff base construction. Ethanol was used as both the solvent and an inexpensive TH reagent, where a broad substrate scope was demonstrated for these tandem reactions. All reactions proceeded smoothly in air at 80-90 °C. The RhIII-PdII complex showed superior catalytic performance in comparison to the RhIII-PtII complexes, its monometallic counterparts, and mixtures of monometallic (RhIII + PdII) complexes. The result demonstrates a cooperative effect between the Rh and Pd metal centers. A mechanism for the catalytic tandem reactions was investigated. It was found that alcohol medium and base are essential.
