The research that will be presented in this paper concerns the synthesis and testing of a bimetallic homogenous catalytic system based on a tetraphosphine ligand system. The procedure involves four different aspects: ligand synthesis, separation of racemic- and meso-et, ph-P4 ligand, preparation of the dirhodium catalyst, and hydroformylation catalysis. The research introduced me to air-sensitive organometallic synthetic procedures, organophosphine and transition metal chemistry, and catalysis concepts that I had no prior knowledge. I became proficient in the inert atmosphere synthetic techniques, and a variety of laboratory equipment and was able to complete most of the project with minimal assistance. I successfully synthesized the binucleating tetraphosphine ligand and dirhodium catalyst precursor and studied bimetallic cooperativity in hydroformylation catalysis. For future research, we hope to perform additional catalytic runs, compare the catalyst to other monometallic rhodium catalysts, and to determine better reaction conditions for the hydrogen producing aldehyde-water shift catalysis.
