  Preparation of halogeno(pentafluorophenyl)silanes (C6F5)nSiX4−n (X=F, Cl and Br; n=2, 3) from pentafluorophenyl(phenyl)silanes (C6F5)nSiPh4−n

  摘要：

  Halogeno(pentafluorophenyl)silanes (C6F5)nSiX(4-n) (X = F, Cl and Br; n = 2, 3) were prepared in good yields from the corresponding phenylsilanes (C6F5)(n)SiPh4-n by reactions with the electrophiles aHF, FSO3H, HCl-AlCl, 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. (C) 1998 Elsevier Science S.A.

  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.

  通过依次用SOCl 2进行氯脱乙氧基化并用SbF 3氟化氯硅烷，由相应的乙氧基硅烷制备五氟苯基（氟）硅烷（C 6 F 5）n SiF 4-n（n = 1，2）。描述了用无水HF将C 6 F 5 Si（OEt）3和C 6 F 5 SiCl 3转化为C 6 F 5 SiF 3。研究了C 6 F 5 SiF 3与亲电试剂和亲核试剂的一些反应。
