Abstract

The first known example of a novel wide-bite angle phosphorus ligand paired with a crown ether system has been prepared. This thesis examines the relevant history of phosphine ligands and crown ethers, as well as the synthetic steps taken to derive this fascinating molecule. Examination of the molecule by both nuclear magnetic resonance (NMR) and elemental analysis has revealed that the molecule has been isolated, and can be complexed with either a transition metal or an alkaline earth metal. The special structure of this ligand could have a great impact on the stability and reactivity of various transition metal complexes, as the crown ether system imparts "tunability" on the molecule, which is dependant upon the size and shape of the ion that is complexed. In addition, the ability of this molecule to transport transition metals between aqueous and non-aqueous solutions is an exciting topic of future study.
