Abstract

Compounds of the new tetrafluorophthalimido anion, [C₆F₄(CO)₂N]^-, are readily accessible by treatment of tetrafluorophthalimide with either LiNPrⁱ₂ or mixtures of NEt₃ and Me₃ECl (E = Si or Sn), to give C₆F₄(CO)₂N-X (X = Li 3, SiMe₃4, and SnMe₃5). The reaction of the trimethylsilyl derivative 4 with AgF leads cleanly to the ion pair complex [Ag(NCMe)₂][Ag(N(CO)₂C₆F₄)₂] (6·2MeCN), which contains a linear [Ag{N(CO)₂C₆F₄}₂]^- anion and a tetracoordinate Ag⁺ cation. Compound 6 reacts with iodine to give the N-iodo compound C₆F₄(CO)₂NI 7, which crystallises as an acetonitrile adduct. Treatment of 6 with LAuCl affords LAu{N(CO)₂C₆F₄} (L = Ph₃P 8a, Cy₃P 8b, or THT 9), whereas the reaction with AuCl in acetonitrile affords the heterobinuclear compound [Ag(MeCN)₂][Au{N(CO)₂C₆F₄}₂]·MeCN (10·3MeCN). The tetrafluorophthalimido ligand is not readily displaced by donor ligands; however, the addition of B(C₆F₅)₃(Et₂O) to a diethyl ether solution of 8a leads to the salt [Au(PPh₃)₂][N{COB(C₆F₅)₃}₂C₆F₄)] 11. The analogous reaction of (THT)Au{N(CO)₂C₆F₄} with B(C₆F₅)₃ in toluene in the presence of excess norbornene (nb) gives [Au(nb)₃][N{COB(C₆F₅)₃}₂C₆F₄)] 12. Compounds 11 and 12 contain a new non-coordinating phthalimido-bridged diborate anion with O-bonded boron atoms. The crystal structures of compounds 2–11 are reported.
