Abstract Details

2017, Master of Science in Chemistry, Youngstown State University, Department of Chemistry.
The gas-phase ligand exchange reactions incorporating main group and transition metal ß-diketonate complexes were investigated using a Finnigan TSQ 7000 triple quadrupole electron impact mass spectrometer. Specifically, trivalent iron and aluminum complexes were reacted with a variety of other metal ß-diketonates during mass spectrometric analysis, and the ensuing gas-phase reactions were shown to generate a variety of products. Relative peak heights of parent ions in the resultant cosublimation spectra were compared to the reactants’ baseline spectra to discern the relative reactivity of each parent ion, and subsequently, propose reaction mechanisms accounting for the production of mixed ligand products. To attain a more complete understanding of certain gas-phase reactions, tandem mass spectrometry was implemented to study selective reactions between specific parent ions and a neutral gas species. Analysis and interpretation of the resulting spectra allowed for the formulation of specific reaction mechanisms for each product detected. Finally, for the first time, the mechanism of partial ligand exchange was proposed and modeled using the PM3 semiempirical method to elucidate general features thought to be employed during the simultaneous mass analysis of homo-metal ß-diketonates.
