- Preparation of halogeno(pentafluorophenyl)silanes (C6F5)nSiX4-n (X=F, Cl and Br; N=2, 3) from pentafluorophenyl(phenyl)silanes (C6F5)nSiPh4-n
-
Halogeno(pentafluorophenyl)silanes (C6F5)nSiX4-n (X=F, Cl and Br; n=2, 3) were prepared in good yields from the corresponding phenylsilanes (C6F5)nSiPh4-n by reactions with the electrophiles aHF, FSO3H, HCl-AlCl3 or with AlX3 (X=Cl, Br)-halogenated hydrocarbons. The relative leaving ability of the organyl groups (C6F5, C6H5, Me) bonded to the silicon atom and the strength of the electrophilic reagent are discussed.
