Abstract:
1. Process for preparing a compound of the general formula (I) in which A is CH, D is CH, E is N, C—CF X with the proviso that A, D and E do not all simultaneously have the same definition, by reacting a compound of the general formula (II) in which A′ is CH, D is CH, E is N, C—CF X Hal is Cl, Br or I, with the proviso that A, D and E do not all simultaneously have the same definition, with a fluoride in the presence of at least one compound of the general formula (III) in which A is a radical of the formulae (IV) or (V) and B, independently of A, is a radical of the formulae (IV), (V), (VIa) or (VIb)  where  the individual R  where one or more NR  where the formula (IV) and the  group in formula (VIa) may also be a radical of a saturated or unsaturated 4- to 8-membered ring which contains two nitrogen atoms and otherwise carbon atoms, X is N or P and An characterized in that the reaction is effected in one stage.
