REACTIONS OF PENTAFLUOROANILINE WITH AROMATIC TRIHALOMETHYL DERIVATIVES IN THE PRESENCE OF ALCL3

The reactions of pentafluoroaniline with aromatic CX(3)-derivatives (X = F, Cl) in the presence of AlCl3 were studied. It was shown that com pounds with a CF3 group can be used 3 in reactions with polyfluoroarom atic amines instead of CCl3-derivatives for the synthesis of imidoyl c hlorides. In the case of compounds with several CX(3) groups, the form ation of the 3 imidoyl chloride moiety predominantly involves one of t he CX(3) groups under the conditions studied. The introduction of a se cond CX(3) group can be carried out only under more drastic conditions .
