実験手順

Under a nitrogen atmosphere, 10.1 g (0.44 mol) of sodium was dissolved in 200 ml of 2,2,2-trifluoro ethanol in 300 ml of a three-necked flask, to which 40 ml (0.38 mol) of p-fluoronitro benzene was dropped and refluxed for 4 hours. After cooling to a room temperature, water was poured (about 1 liter), and precipitated solids were washed with water and dried, to obtain p-(2,2,2-trifluoroethoxy) nitrobenzene (yield: 62%; and melting point: 76.5° C.).
