Halogen- and chalcogen-based σ-hole interactions have recently received increased interest in non-covalent organocatalysis. However, the closely related pnictogen bonds have been neglected. In this study, we introduce conceptually simple, neutral, and mon

The substitution of hypervalently bonded fluorine atoms in C 6F5IF4 was performed with C6F 5BF2 and resulted in the new salt [(C6F 5)2IF2][BF4]. The iodonium(V) salt was characterized by multi-NMR and Raman spectroscopy and X-ray crystal structure analysis. The fluorinating ability of the new electrophilic cation [(C6F5)2IF2]+ was exemplified in reactions with monovalent iodine compounds (C6F 5I, p-FC6H4I, and I2) and with electron-poor tri(organyl)pnictanes ER3 (E = P, As, Sb, Bi; R = C6F5). In a heterogeneous reaction with CsF in MeCN the [(C6F5)2IF2]+ cation forms the dinuclear [{(C6F5)2IF 2}2F]+ cation.

AgC6F5 is directly and quantitatively formed from room temperature reactions of AgF and Me3SiC6F5 in N-donor solvents, particularly EtCN. Solutions of AgC6F5 prepared by this method exhibit excellent oxidative properties in reactions with a variety of groups 12 to 16 elements giving the corresponding pentafluorophenyl element compounds in moderate to excellent yields. AgC6F5·EtCN crystallises with monoclinic symmetry (C2/c, Z = 8, a = 2301.4(5)pm, b = 1078.8(4)pm, c = 948.0(2)pm, β = 113.19(1)°) and exhibits chains of silver atoms with bridging C6F5 groups.

(C6F5)3Sb has been found to react with interhalogens and halo-pseudohalogens, IX(X = Cl, Br, N3 and NCO), pseudohalogen (SCN), and elemental sulphur to give oxidative addition products (I-VI). (C6F5)3SbS(VI) may also be prepared by the reaction of (C6F5)3SbCl2 with H2S. Metathetical reactions of (C6F5)3SbCl2 with appropriate metallic salts yield covalent pentacoordinate disubstituted products (V, VII-XII) of the general formula, (C6F5)3SbY2 (Y = NCS, NCO, -ONCMe2, -ONCMePh -NCO(CH2)2CO and p-NO2C6H4OCO). Treatment of (C6F5)3SbCl2 with aqueous NaN3 gives the binuclear oxo-bridge compound, [(C6F5)3SbOSb(C6F5)3](N3)2·(III) and (IV) are also accessible by displacement reaction of (I) or (II) with the corresponding metallic salt. Molecular weight, conductance measurements, and IR spectra on the new organoantimony(V) derivatives have been obtained. Reductive cleavage reactions of (C6F5)3SbS with hexaaryldileads, Ar6Pb2(Ar = Phenyl, p-tolyl) produce (C6F5)3Sb and the corresponding bis(triaryllead) sulphide but treatment of (C6F5)3SbX2(X = NCO, Cl) with Ar6Pb2 gave Ar4Pb and Ar2PbX2 together with (C6F5)3Sb. (C6F5)3SbCl2 and bis(triorganotin)sulphides undergo exchange of anionic groups.
Organothallium compounds. VI. Reactions of bromobis(pentafluorophenyl)thallium(III) with main group elements

Bromobis(pentafluorophenyl)thallium(IlI) reacts with many main group elements on heating in the absence of a solvent to give pentafluorophenyl derivatsves of these elements. The compounds C6F5M (M = Cl, Br, or I), (C6F5)2M (M = Zn, Cd, Hg, S, Se or Te), (C6F5)3M (M = In, P, As, or Sb), and (C6F5)M (M = Ge or Sn) have been prepared by this method. Substantial decomposition of (C6F5)2TlBr occurs on reaction with aluminium, gallium, lead and bismuth, but pcntafluorophenyl derivatives of these elements are not obtained.
