Synthesis and structures of gold perfluorophthalimido complexes
Compounds of the new tetrafluorophthalimido anion, [C6F 4(CO)2N]-, are readily accessible by treatment of tetrafluorophthalimide with either LiNPri2 or mixtures of NEt3 and Me3ECl (E = Si or Sn), to give C 6F4(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 C6F 4(CO)2NI 7, which crystallises as an acetonitrile adduct. Treatment of 6 with LAuCl affords LAu{N(CO)2C6F 4} (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(C 6F5)3(Et2O) to a diethyl ether solution of 8a leads to the salt [Au(PPh3)2][N{COB(C 6F5)3}2C6F4)] 11. The analogous reaction of (THT)Au{N(CO)2C6F 4} with B(C6F5)3 in toluene in the presence of excess norbornene (nb) gives [Au(nb)3][N{COB(C 6F5)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.
