polyfluoroaryl的反应溴化物的Ar ˚F Br或碘化物的Ar ˚F我与P(NR' 2)3和R 3 MX(R =烷基; M =硅,锗,锡,和铅; X =氯,溴)导致了Ar F MR 3的形成。C 6 F 5 Br与P(Net 2)3和C-亲电试剂(CH 3 I,C 6 F 5 CF 3和(CF 3)2 C = CFC 2 F 5)的反应产生了五氟苯基化产物基材。
The reactions of polyfluoroaryl bromides ArFBr or iodides ArFI with P(NR′2)3 and R3MX (R = alkyl; M = Si, Ge, Sn, and Pb; X = Cl, Br) led to the formation of ArFMR3. The reactions of C6F5Br with P(Net2)3 and C-electrophiles (CH3I, C6F5CF3 and (CF3)2C=CFC2F5) gave the products of pentafluorophenylation of these substrates.

The rate of replacement of the halogen atom in isomers of RC6F4X (X=Cl, Br, or I) by the SiMe3 group under the action of Me3SiCl and P(NEt2)3 depends on the nature and the mutural arrangement of the substituents X and R. In addition to silyldehalogenation, compounds C6HF4X (X=Br or I) undergo silyldeprotonation and reduction to tetrafluorobenzenes.
