| Abstract: | Fluoroalkyl captodative compounds, e.g., 4-MeOC6H4OCH2CF2CHF2 and Pr2NCH2CF3 are prepared Their anions induce the reaction of perfluoroalkyl iodides with olefins to give mainly fluoroalkenes. This reaction is accelerated by UV irradiation and partly suppressed by p-dinitrobenznene. Diallyl ether traps the radical intermediates to afford THF derivatives A single electron transfer mechanism is proposed. |
