- Abstract:
- Two distinct projects, both involving the cyclopentadienyl ligand, are herein presented.;First, in an effort to develop a general synthetic route to ansa-chromocene complexes with diverse ligand frameworks, ansa-magnesocene compounds were investigated as an alternative to ansa-calcocene compounds, offering a potentially more versatile ligand source than used previously. This synthetic pathway allowed the preparation of the novel single carbon-bridged ansa-chromocene (II) carbonyl complex, and revealed a route for synthesizing ansa-chromocene complexes with diverse ansa ligand framework. A simple and direct route to deuterium-labeled calcocene compounds was also discovered. The resulting labeled cyclopentadienyl ligand may be directly transferred to d- or f-block metals.;Second, a variety of gallocene azo compounds have been prepared and characterized to study their potential as single source precursors to gallium nitride nanomaterials. In the course of this work, the nature of the nitrogen delivery source and variation of the extent of substitution of the cyclopentadienyl ligand on the gallium compounds were observed to significantly affect the ability to isolate discrete bis(cyclopentadienyl)gallium azo derivatives. Preliminary decomposition studies were also undertaken and revealed that the use of cyclopentadienyl ligand lowers the decomposition temperature of the gallium compounds relative to other gallium alkyl compounds.
