Selective elemental fluorination in ionic liquids (ILs) will be presented as a new methodology. The tested reagents are organic disulphides and organic iodides. In addition, the stabilities of the ionic liquids [EMIM][(C 2F5)3PF3], [BMPL][(C 2F5)3PF3], [BMPL][OTf] and [BMPL][B(CN)4] against diluted fluorine (5 vol% in nitrogen) are investigated.
A first methodical approach to salts with unsymmetrical fluorophenyl(pentafluorophenyl)difluoroiodonium(V) cations [Rf(R F)IF2]+ (Rf=x-FC6H 4, x=2, 3, 4; RF=C6F5)

A promising approach to the unknown type of [Ar′(Ar)IF2]X salts is offered. x-FC6H4IF4 (x=2, 3, 4) reacts with C6F5BF2 in CH2Cl2 and forms [x-FC6H4(C6F5)IF 2][BF4] salts in good yields. For [4-FC6H 4(C6F5)IF2][BF4] the fluoro-oxidizer property is shown in reactions with weakly reducing agents like E(C6F5)3 (E=P, As, Sb, Bi) and ArI (Ar=4-FC6H4, C6F5). The fluorine/aryl substitution method is also applied to the synthesis of [(4-FC6H4)2IF2][BF4], an example with two identical aryl groups in the difluoroiodonium(V) moiety.

The aryl iodides C6H5I, o-XC6H4I(X = F, I), m-FC6H4I and p-XC6H4I (X = F, Cl, Br, I, CH3, NO2) react with elemental fluorine at about -100 deg C in CCl3F to form the corresponding aryl iodine difluorides without attack on the aromatic ring.Preparations, (
