By a method similar to Example 11, a reaction was carried out using 2,4,5,6-tetrafluoroisophthalonitrile, instead of 3,4,5,6-tetrafluorophthalonitrile. After 5 hours, the reaction solution was analyzed by gas chromatography, whereupon the conversion of 2,4,5,6-tetrafluoroisophthalonitrile was found to be 36% and the yield of 2,3,4,6-tetrafluorobenzonitrile (based on 2,4,5,6-tetrafluoroisophthalonitrile) was 20%. At the same time, 1.1 mmol of α-methylbenzylcyanide was produced. This corresponded to 0.35 times molar amount relative to the production of 2,3,4,6-tetrafluorobenzonitrile.
