참여 물질

반응 단계

A solution of 1.2 g (10×10-3 mol) of 2,6-dimethylphenol in 40 ml of acetonitrile was dropwise added at a temperature of -10° C. to a solution of 2.0 g (10×10-3 mol) of tetrafluoroisophthalonitrile and 2.9 g (50×10-3 mol) of potassium fluoride. The mixture was allowed to stand at a temperature of -10° C. to 0° C. for 1 hour while stirring and the undissolved potassium fluoride was separated by filtration. The filtrate was concentrated to dryness in vacuo. The resultant residue was dissolved in a mixed solvent of acetone and cyclohexane and 2.3 g (77% yield) of the desired compound No. 37 was obtained as white crystal.
