Abstract

This dissertation discusses three new types of polymer bound catalysts and their applications. The first type is a polymer bound cation that is an effective spectator ion for nitrate. The nitrate ion is then free to act as a catalyst in aza and thia-Michael reactions and Strecker reactions. The second catalyst was previously reported. However, its structure was incorrectly assigned. The correctly revised structure of the polymer bound azidoproazaphosphatrane shows impressive catalytic activity in the oxa-Michael reaction. The third catalyst is a polymer bound free proazaphosphatrane. It is shown to be catalytically active in the trimerization of an isocyanate to an isocyanurate and in the synthesis of a diaryl ether. Finally, two interesting reactions are reported where proazaphosphatranes are shown to increase the reactivity of silicon compounds. The first is the production of cyanohydrins and protected cyanohydrins where and activated trimethylsilylcyanide adds to aldehydes and ketones. The second is reduction of aldehdyes and ketones with the use of poly(methylhydrosiloxane).
