Retrospective Theses and Dissertations
Polystyrene bis(salicylaldehyde)-propylene-1,3-diiminato Cobalt (II) [salen] and Polystyrene bis(2,4-pentanedione)-propylene-1,3-diiminato Cobalt (II) [BAE] were prepared stepwise from chloromethylated polystyrene. In addition, a new preparation of a Schiff base was attempted resulting in Polystyrene bis(salicylaldehyde)-isobutylene-1,3-diiminoato Cobalt (II) being produced. Optimum reaction conditions were determined with regard tot ime, temperature, reaction ratios and solvent for each step for the reaction. The ability of the above named Cobalt (II) Schiff bases to oxidize 3-methyl indole to give the corresponding o-formylaminoacetophenone was also studied. One polymer-bound Schiff base cobalt catalyst (co-salen) demonstrated a very small amount of catalytic activity resulting in a minimum amount of o-formylaminoacetophenone …
