Synthesis and characterization of rhodium–aluminum heterobimetallic complexes tethered by a 1,3-bis(diphenylphosphino)-2-propanoxy group

Abstract

We demonstrate the synthesis and characterization of a new class of late transition metal-aluminum heterobimetallic complexes. A bridging ligand which both chelates the transition metal and binds the aluminum via an alkoxide was employed to impart stability to the bimetallic system. Novel rhodium–aluminum heterobimetallic complexes Rh(DPPE)(DPPP-O-AlⁱBu₂Cl) and Rh(DPPP-O-AlⁱBu₂)(DPPP-O-AlⁱBu₂Cl) are synthesized and spectroscopically characterized.
