Claim:
A process for preparing a compound(s) of the formula (IV) Ar—(F-R2) n (IV) in which n is 1, 2 or 3and Ar is a substituted or unsubstituted aromatic radical and F is oxygen, sulphur, NR 3 , NR 3 CO or ethyndiyl, where R 3 is hydrogen, C 1 –C 12 -alkyl, C 5 –C 18 -aryl or C 6 –C 19 -arylalkyl and R 2 is Ar, C 1 –C 12 -alkyl, C 1 –C 12 -haloalkyl, C 2 –C 12 -alkenyl or C 6 –C 19 -arylalkyl, comprising reacting a compound(s) of the formula (V) Ar-Z (V) in which Ar is as defined above and Z is chlorine, bromine, iodine, a diazonium salt or sulphonate with a compound(s) of the formula (VI) H—F—R 2 (VI) in which F and R 2 are each as defined above and in the presence of base and a compound(s) of the formula (I) in which Het 1 , Het 2 and Het 3 are each independently absent, or are oxygen or NR 1 where R 1 is C 1 –C 8 -alkyl, C 5 –C 18 -aryl or C 6 –C 19 -arylalkyl and B 1 and B 2 are each independently C 1 –C 8 -alkyl, C 5 –C 18 -aryl or C 6 –C 19 -arylalkyl, or the B 1 and B 2 radicals together are a divalent radical having a total of 2 to 40 carbon atoms and B 3 is C 1 –C 8 -alkyl, C 5 –C 18 -alkyl, C 6 –C 19 -arylalkyl or a radical having a total of 2 to 40 carbon atoms and the valency n, Xis halide, (C 1 –C 8 -haloalkyl)carboxylate, (C 1 –C 8 -alkyl)carboxylate, (C 1 –C 8 -haloalkyl)sulphonate, (C 5 –C 18 -aryl)sulphonate, cyanide, optionally fluorinated acetylacetonate, nitrate, oxinate, phosphate, carbonate, hexafluorophosphate, tetraphenylborate, tetrakis(pentafluorophenyl)borate or tetrafluoroborate, and p is 0, 1, or 2 and n is 1, 2or 3 and m is 1, 2, 3, 4, 5 or 6.
