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.

A convenient preparation of pentafluorophenyl( fluoro) silanes: Reactivity of pentafluorophenyltrifluorosilane

Pentafluorophenyl(fluoro)silanes (C6F5)nSiF4-n (n = 1, 2) were prepared from the corresponding ethoxysilanes by sequential chlorodeethoxylation with SOCl2 and fluoridation of chlorosilanes with SbF3. The conversion of C6F5Si(OEt)3 and C6F5SiCl3 into C6F5SiF3 with anhydrous HF was described. Some reactions of C6F5SiF3 with electrophiles and nucleophiles were studied.
