A Two Part Research Report: Aromatic Nucelophilic Fluoroal Koxylation Via Cationic Phase Transfer Catalysis And Reactions Of Unsymmetrical Vinamidinium Salts With Organometallic Reagents, Joseph E. Coury
Retrospective Theses and Dissertations
This report discusses research which was conducted in two areas: the study of aromatic nucleophilic fluoroalkoxylation assisted via cationic phase transfer catalysis and the study of unsymmetrical vinamidinium salts and their reactions with organometallic reagents.
Sodium alkoxides have been successfully used to fluoroalkoxylate activated halo- aryl and heteroaryl substrates under phase transfer catalysis conditions. Optimum reaction conditions incorporated tetra-n-butyl-phosphonium bromide as the catalyst and refluxing toluene as the solvent medium. Different quarternary phosphonium and arrmonium salts have been evaluated as catalysts: also, the effects of activating groups, leaving groups, and nucleophiles have been reported.
