This thesis deals with the syntheses and structures of organoaluminum amides and imides using polydentate amines. Various bidentate and tridentate amines were reacted with trimethylaluminum to yield complexes with uncommon structural features. The reaction between trimethylaluminum and N-phenylethylenediamine produces a monomeric dialkylaluminumamido complex and a trimeric monoalkylaluminumamido complex. The structures of $\rm Me\sb2Al(NH\sb2,CH\sb2CH\sb2NPh),$ 2.1, and $\rm (MeAl(NHCH\sb2CH\sb2NPh))\sb3,$ 2.2 are presented. The reaction between trimethylaluminum and 8-aminoquinoline in a 1:2 ratio affords a monomeric monoalkylaluminumamido complex, while in a 2:1 ratio a tetranuclear imido complex is formed. Reaction of this tetranuclear complex with one equivalent of molecular oxygen converts a methyl group to a methoxy group and results in the formation of a new tetranuclear species. The structures of MeAl(8-amidoquinoline)$\sb2$ 3.1, $\rm Me\sb8Al\sb4(\mu\sb3$-8-imidoquinoline)$\sb2$ 3.2, and $\rm Al\sb4(\mu\sb3$-8-imidoquinoline)$\rm\sb2(CH\sb3)\sb7(OCH\sb3)$ 3.3 are presented. The reaction between 2-(aminomethyl)pyridine and trimethylaluminum affords a chelated dimeric dialkylaluminumamido complex. The analogous reaction with 4-(aminomethyl)pyridine also produces a dimeric dialkylaluminumamido complex but in this species the pyridine group does not chelate. The structures of (Me$\sb2$Al(2-(amidomethyl)pyridine)) $\sb2$ 3.4, and (Me$\sb2$Al(4-(amidomethyl)pyridine)) $\sb2$ 3.5 are presented. The reactivity of some tridentate amines was also investigated. The reaction between trimethylaluminum and tetraethyldiethylenetriamine (tedtaH) in a 1:1 ratio produces a mononuclear dialkylaluminumamido chelate complex, while a 3:1 ratio affords a trinuclear species. The structures of Me$\sb2$Al(tedta) 4.1, and $\rm Me\sb8Al\sb3$(tedta) 4.2 are presented. The reaction between trimethylaluminum and di(2-pyridylmethyl)amine (dpaH) produces a mononuclear complex similar to 4.1. The structure of Me$\sb2$Al(dpa) 4.3 is presented.Dept. of Chemistry and Biochemistry. Paper copy at Leddy Library: Theses & Major Papers - Basement, West Bldg. / Call Number: Thesis1994 .T735.
