Dr. George Stanley from Louisiana State University will present "Bimetallic Cooperativity in Catalysis: Twice the Fun!" 3:10 pm in the Byler. Professor Sharon Neufeldt is the host.
Abstract: Homobimetallic rhodium complexes using the binucleating tetraphosphine ligand racemic-(Et2PCH2CH2)(Ph)PCH2P(Ph)(CH2CH2PEt2), et,ph-P4, are highly active and selective hydroformylation catalysts for a variety of 1-alkenes. We have investigated the nature of the bimetallic cooperativity in this novel catalyst via extensive in situ FT-IR, NMR, kinetic, isotopic labeling experiments, and DFT computational studies, all of which indicate that the key bimetallic catalyst in acetone is a unique dicationic Rh(+2) oxidation state complex, [rac-Rh2(m-H)2(CO)2(et,ph-P4)]2+. Unfortunately, the NMR studies clearly indicate that this catalyst system is very susceptible to deactivating fragmentation reactions.
When a 30% water/acetone solvent system is used for hydroformylation deprotonation of the dicationic dihydride species occurs generating a less active, but far more fragmentation resistant bimetallic catalyst proposed to be [Rh2(m-H)(CO)2(et,ph-P4)]+, which out-preforms the dicationic catalyst. Based on the fragmentation problem a new, far more strongly coordinating P4 ligand that uses 1,2-phenylene based chelating groups has been designed, synthesized, and characterized. Studies on bimetallic complexes based on this new P4 ligand will be discussed.
