Abstract:Die mw‐Diiodperfluoralkane (I) werden durch Trifluorperessigsäure in die Tetrakistrifluoracetylderivate (II) übergeführt, die mit Benzol bzw. mit Toluol zu den Bisaryliodoniumtrifluoracetaten (III) bzw. (IV) umgesetzt werden und mit SP4 die a,w‐Bisdifluoriodperfluoralkane (V) liefern.
“…The ethane derivative (n = 1) reacted with benzene to yield the corresponding diiodonium salt, whereas the reaction with toluene occurred too rigorous and gave tar. The butane derivative (n = 2) did not react with C 6 H 6 whereas the reaction with C 6 H 5 CH 3 was completed after 14 d. The hexane derivative (n = 3) did neither react with benzene nor with toluene [38] (Eq. (33))…”

“…The yield of 167 from this reaction was low (26%), and a considerable amount of 168 was recovered. Stabilization of the cationic sulfur atom in intermediate 169 by resonance with the ether oxygen Scheme 6 (45) Scheme 7 (46) (47) ( at the o-position may account for the slowness of this reaction. 66b…”

“…Yagupolskii et al synthesized a series of perfluoroalkylene bis(phenyl- and bis( p -tolyliodonium trifluoroacetates) and tetrafluoroborates) 108 − 111 from 106 or α,ω-bis(difluoroiodo)perfluoroalkanes 107 (eq 31). 12b, The reactions of sodium p -chlorothiophenolate with 110 and 111 produced α,ω-bis[( p -chlorophenyl)thio]perfluorobutane and -hexane in 81% and 68% yields, respectively. …”
“…In the case of ICF 2 CF 2 I, the oxidation with peroxytrifluoroacetic acid or tert -perfluorobutyl hypochlorite 529 led to bis(aryliodonio)perfluoroethanes 528a and 528c . The reaction of 528a with benzene in trifluoroacetic acid led to iodonium salt 528b in 64% yield to link two benzene rings (Scheme ).…”
