  [Ar(Ar′)I][N(CF3)2], effect of fluorine substituents on aryl groups of iodonium cations and of coordinating bases on the fluoride transfer from the anion to the cation

  摘要：

  Three prototypical fluoroaryliodonium salts with the (N(CF3)(2)](-) anion were obtained by metathesis in the corresponding tetrafluoroborate salts [Ar(Ar')I][BF4](Ar/Ar' = C6H5/4-FC6H4, 3-FC6H4/4-FC6H4, C6F5/C6F5) with in situ generated Rb[N(CF3)(2)]. The kinetic lability of the [N(CF3)(2)](-) anion (potential fluoride donor like [OCF3](-)) in combination with the gradual change in fluoride affinity of the three [Ar(Ar')]I](+) fluoroaryliodonium cations allowed to distinguish the fluoride acceptor property of the three (Ar(Ar')I](+) fluoroaryliodonium cations. Coordinating solvents or ligands suppressed the fluoride transfer from the [N(CF3)(2)](-) anion to the fluoroaryliodonium cation. (C) 2012 Elsevier B.V. All rights reserved.
