Coordination of Dibenzothiophehes and Corannulenes to Organometallic Ruthenium (II) Fragments

摘要

This dissertation contains five papers in the format required for journal publication which describe (in part) my research accomplishmentsas a graduate student at Iowa State University. This work can be broadlycategorized as the binding of weakly-coordinating ligands to cationic organometallic ruthenium fragments, and consists of two main areas of study. Chapters 2-4 are investigations into factors that influence the binding of dibenzothiophenes to (l(underline)brace)Cp'Ru(CO)(sub 2)(r(underline)brace)(sup +) fragments, where Cp' = (eta)(sup 5)-C(sub 5)H(sub 5) (Cp) and (eta)(sup 5)-C(sub 5)Me(sub 5) (Cp*). Chapters 5 and6 present the synthesis and structural characterization of complexes containing corannulene buckybowls that are (eta)(sup 6)-coordinated to (l(underline)brace) Cp*Ru(r(underline)brace)(sup +) fragments. The first chapter contains a brief description of the difficulty in lowering sulfur levels in diesel fuel along with a review of corannulene derivatives and their metal complexes. After the final paper is a short summary of the work herein. Each chapter is independent, and all equations, schemes, figures, tables, references, and appendices in this dissertation pertain only to the chapter in which they appear.
