I :Synthesis and Evaluation of Polymer Supported Homogenous Oxidation Catalysts. II: Synthesis and Evaluation of Polymer Supported Multi Site Phase Transfer Catalysts III: Synthesis of Potential Herbicides

Leonard, Russell L. 01 January 1984 (has links) (PDF)
This report consists of three parts. Part I involved the synthesis and evaluation of some polymer supported homogeneous oxidation catalysts – specifically, the synthesis of polystyrene 2(bis-salicylaldehyde) 2-methyl propylene-1, 3-diiminato cobalt (II) and polystyrene 2(bis-2, 4-pentanedione) 2-methyl propylene-1, 3-diiminato cobalt (II). Part II involved the synthesis of both soluble and insoluble phase transfer catalysts designed to catalyze nucleophilic substitution reactions. Trisite quaternary phosphonium and disite quaternary phosphonium salts were prepared. Part III involved the synthesis of several potential herbicides.
