- Reactions of methyl(pentafluorophenyl)- and methyl(pentafluorophenyl)phenylsilanes with electrophiles. A convenient preparative route to halogeno(methyl)pentafluorophenylsilanes C6F5SiMe2X and C6F5SiMeX2 (X=F, Cl and Br)
-
Halogeno(methyl)pentafluorophenylsilanes C6F5SiMenX3-n (n=1, 2) (X=F, Cl, Br) were prepared in good yields from the corresponding phenylsilanes C6F5SiMenPh3-n by reactions with the electrophiles aHF, HCl-AlCl3, Br2-AlBr3 or AlX3 (X=Cl, Br) halogenated hydrocarbons. Additionally, reactions of C6F5SiMe3 and (C6F5)2SiMe2 with selected electrophiles were studied.
