A convenient and practical method for the preparation of fluoroalkylarylethers via substitution of iodoalkyl fluorides is described. This method involves KF complexation of the phenol, which increases the nucleophilicity of oxygen for the formation of the ether linkage.
Tetrafluoroalkyl bromides are metalated with equimolar iPrMgCl·LiCl (Turbo Grignard) to form organomagnesium compounds which are stable at low temperatures and react with various electrophiles (aldehydes, ketones, CO2, cyclic sulfate and sulfamidate, N-sulfonylimines, nitrone, chlorophosphate, nonaflyl azide) to afford novel functionalized tetrafluoroethylene-containing products.
