Polynuclear Au (I) complexes exhibit rich photochemical properties and have the potential to find applications as molecular sensors, switches, or energy storage devices. Although dinuclear Au (I) complexes with bridging diphosphines have been extensively examined, most of those reported do not contain rigid-diphosphine ligands.
This thesis examines how the rigid diphosphine, 4,6-bis(diphenylphosphino)dibenzofuran (DBFDP) can be incorporated for the controlled assembly of photoluminescent gold (I) metal – chalcogenolate (chalcogenolate = RS-, RSe-; R = organic moiety) and gold (I) chalcogenide (chalcogenide = S2-, Se2-) bimetallic complexes. In these studies, the chalcogen …

N-Acyl ketenimines were attempted to be synthesized catalytically by [Ru(Cp)(PPh2NPh2)(NCMe)]PF6 with phenylacetylene and 3-phenethynyl-1,2,4-dioxazol-5-one. Trapping agents were employed to identify the major product of the reaction, as many products were formed. [Ru(Cp)(PPh2NPh2)(NCMe)]PF6 reacts with 3-phenethynyl-1,2,4-dioxazol-5-one generating an isocyanate via the Curtius rearrangement, confirmed by a forced Curtius rearrangement with 3-phenethynyl-1,2,4-dioxazol-5-one and 1,2,4-triazole. Rates of vinylidene formation using [Ru(Cp)(PPh2NPh2)(NCMe)]PF6 and various terminal alkynes of different sterics and electronics were evaluated using a Hammett analysis for and simple rate comparisons. …
