Dr. Gerrick Lindberg (Northern Arizona) will present a seminar titled "Controlling the structure of proteins with ionic liquids." Dr. Lindberg is the guest of Professor Sharon Neufeldt.

Abstract: Ionic liquids (ILs) have received significant attention in the past few decades as a novel class of materials with numerous proposed technological applications. ILs are salts that are liquid at the operating temperature; for room temperature operation this typically entails a large organic cation and a smaller anion. At the crux of their interesting behavior is the fact that they are typically polar and organic, so ILs can be designed with attributes of both aqueous and organic solvent environments. Despite all of the promise and research, there remain fundamental questions about the behavior of ILs. One particularly tantalizing area has been the use of ILs in biological systems. Recent publications from my and other groups have shown that ILs can have dramatic effects on protein structure and cell membrane permeability, but those effects are dependent on the specific system in consideration. In my group we use computational molecular dynamics simulations to predict the behavior of these systems. These techniques provide an unparalleled perspective on molecular motion at length and time scales that naturally emerge. My talk will review our recent results and future plans.

Friday, October 20 

Dr. George Stanley from Louisiana State University will present "Bimetallic Cooperativity in Catalysis: Twice the Fun!" 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.
