The purpose of this thesis is to examine a potential Mn(II) complex model system and its corresponding oxygenated products. The Schiff base ligands chosen for this study (Figure 3) were of the type believed to be in, the environment of manganese as it exists in the photosynthetic process. The ligand systems employed will be derived from salicylaldehyde and a series of straight-chain diamines and 3,3'-bis (aminopropyl)- amine. / Master of Science
