Procedure

The compound 1,2-Bis(2-cyanophenoxy)benzene was synthesized in the same manner as for 1,2-bis-(4-4-cyanophenoxy)benzene according to Example 1 above, but from 2-fluorobenzonitrile and catechol, except that the synthesis was performed in DMF at 125° C. and over a period of 10 hours. The precipitate was filtered off and washed several times with deionised water. The white product was recrystallized from methanol/water (8:1). The yield was 84.6% of the title compound with the formula: ##STR6##
