Abstract Details

2006, Doctor of Philosophy, University of Akron, Chemistry.
It has been nearly four decades since the synthesis of the first transition metal complexes of N-Heterocyclic carbenes (NHCs) by Öfele and Wanzlick. During this time Arduengo isolated the first free NHC, numerous NHC transition metal complexes have been studied for their catalytic properties, and NHC metal complexes are currently being investigated for their use as potential pharmaceuticals. It is the medicinal applications of NHCs that will be discussed in first portion of this dissertation. Chapter 1 provides a review of recent investigations and results of potential metal NHC pharmaceuticals. The discussion focuses on NHC complexes of silver, gold, and rhodium. In Chapter 2 the challenge of increasing silver NHC stability by ligand modification is discussed. Chapter 3 focuses on the syntheses of several macrocyclic imidazolium salts which serve as precursors for the formation of NHCs. The second portion of this dissertation investigates the Lewis acid-base chemistry and nucleophilic substitution of phosphazenes. Cyclophosphazenes have been studied for well over a century and are of particular interest because of their ability to form high weight inorganic polymers via ring opening polymerization. Chapter 4 provides a background on cyclophosphazenes and their polymerization as well as a discussion of the Lewis acid chemistry of chlorophosphazene trimer. In Chapter 5 the nucleophilic substitution of [NPCl2]3 with imidazole is discussed.
