Replacement of hydrogen or trimethylsilyl group by fluorine and the addition of two fluorine atoms to the aromatic ring were found in the reaction of XeF2 with I-trimethylsilyl-2,3,4,5- or 2,3,4,6-tetrafluorobenzenes in CH2Cl2 under BF3. OEt2 catalysis. Only addition of two fluorine atoms took place in the case of 1-trimethylsilyl-2,3,5,6-tetrafluorobenzene. The isomeric trimethylsilylfluorobenzenes underwent fluorodesilylation, fluorodeprotonation and protodesilylation. The assumed reaction pathways include both cation radicals and arylxenon(II) species as reactive intermediates. (C) 1998 Elsevier Science S.A. All rights reserved.
