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

Polyvalent perfluoroorgano- and selected polyfluoroorgano-halogen(III and V) compounds

“…The bis(pentafluorophenyl)iodonium salt was obtained from C 6 F 5 SiF 3 and [IF 4 ][SbF 6 ] in HSO 3 F. During this conversion C 6 F 5 IF 4 , one of the possible intermediates, could not be detected [69].…”

Bis(perfluoroorganyl)bromonium salts [(RF)2Br]Y (RF=aryl, alkenyl, and alkynyl)

“…Anhydrous HF (aHF) was stored over CoF 3 . Tris(pentafluorophenyl)borane [18], C 6 F 5 SiF 3 [33], C 6 F 5 SiMe 3 [34], Li[C 6 [38], and solutions of cis-C 2 F 5 CF5 5CFBF 2 , trans-CF 3 CF5 5CFBF 2 [39], CF 3 CCBF 2 [40] in PFB or PFP were prepared as described. Salt K[C 6 F 13 BF 3 ] [41] and solutions of C 6 F 5 BF 2 [42] and C 6 F 13 BF 2 [41] in PFB or PFP were prepared by modified procedures (see below).…”

Pentafluoroethylated Compounds of Silicon, Germanium and Tin

“…For this purpose the treatment of E(C 2 F 5 ) 4− n R n ( n= 1–3) with gaseous HCl and HBr, in some cases supported by the addition of catalytic amounts of aluminum or iron halides, turned out to be the most valuable protocol (Scheme ). For the corresponding fluorides as well as iodides a halide exchange utilizing SbF 3 and treatment of the hydrogen derivatives E(C 2 F 5 ) 3 H (E=Si, Ge, Sn) with elemental iodine was more feasible than the use of hazardous HF and hardly accessible HI (Table ) …”
