“Synthesis and Spectroscopic Investigations of Metal Diphosphine Compounds: From Covalent Bonding Models to New Ligand Designs”
Abstract:
Diphosphines are very important ligands in homogeneous transition metal catalysis. In order to expedite diphosphine selection for catalyst discovery and optimization, there is a need to understand how changes in coordination geometry and ligand structure affect electronic properties at the metal. In this talk, I will present phosphorus and chlorine K-edge X-ray absorption spectroscopy (XAS) data used to investigate how changes in coordination geometry, diphosphine bite angle, and trans influence affect metal-phosphorus covalency with the late transition metal ions Ni(II), Pd(II), and Rh(I). I will then present recent synthetic efforts aimed at preparing new metal complexes with chemically non-innocent diphosphine ligands.
Biography:
Scott R. Daly was born in 1980 in Joliet, IL and grew up in a small community north of Ocala, FL. He graduated from North Marion High School in 1998 and enlisted in the United States Army as an M1 tank crewman at the age of 17. He was honorably discharged in August 2001 after three years of active duty service in the 1st Cavalry Division in Ft. Hood, TX. He returned to the Chicago suburbs and went on to receive his B.S. degree in chemistry from North Central College in Naperville, IL. During his time at North Central, Scott performed research with Dr. E. Philip Horwitz at Eichrom Technologies LLC to improve the chromatographic extraction of actinides from soil and water. In 2006, he entered the PhD chemistry program at the University of Illinois at Urbana-Champaign and performed research under the guidance of Professor Gregory S. Girolami. Scott’s research focused on the synthesis and characterization of new chelating borohydride ligands and their use in the preparation of volatile transition metal, lanthanide, and actinide complexes for chemical vapor deposition applications. After receiving his PhD in spring 2010, he began working as a Seaborg Postdoctoral Fellow with Drs. Stosh A. Kozimor and David L. Clark at Los Alamos National Lab in Los Alamos, NM. His research there focused on the use of sulfur K-edge X-ray absorption spectroscopy (XAS) to understand structure-function correlations in dithiophosphinates used for minor actinide extraction processes. In 2012, Scott accepted a faculty position at George Washington University in Washington, DC. In 2014, he moved his research group to the University of Iowa where he is currently an Assistant Professor of Chemistry.
