  Iminophosphoranes with organic groups derived from d-glucose, d-galactose and l-arabinose have been used to prepare gold(III) dichloride complexes via mercurated intermediates, since direct cyclometallation was unsuccessful. Structures and full spectroscopic data are reported. Replacement of one or more of the chloride ligands by PPh3, or by thiosalicylate gave new derivatives. Biological screening showed no enhanced

  [MHCl(CO)(PPh3)3] gives the complexes [Ph2)(CO)(PPh3)2] [M=Ru (1), Os (2)], which contain a four-membered cyclometallated ring. A single-crystal X-ray diffraction study of 2 shows the geometry about osmium to be distorted octahedral with the phosphorus atoms in a meridional arrangement. Both complexes react with CO, which displaces one of the triphenylphosphine ligands, the product from 2 being [Ph2)(CO)2(PPh3)]

  The heteronuclear Au-I/Hg-II complexes [HgAuR(mu-2-C6H4PPh2)}(2)] ER = C6F5 (1), C6Cl2F3 (2)] were prepared by reacting [Hg(2-C6H4PPh2)(2)] with [AuR(tht)] (1:2) and further transformed into the AuIII/HgII species [HgAu(C6F5)Cl-2(mu-2-C6H4PPh2)}(2)] [R = C6F5 (3), C6Cl2F3 (4)] by the addition of 2 equiv of PhI Cl-2. The crystal structures of 1-3 display Au center dot center dot center dot Hg-II interactions, which in the case of 3 is the first Au-III center dot center dot center dot Hg-II contact described to date. Theoretical calculations on model systems of the C6F5 derivatives evidence that the attraction between Au-I or Au-III and Hg-II arise from dispersion-type interactions and that both contacts are of the same strength.
• Synthesis and characterisation of isomeric cycloaurated complexes derived from the iminophosphorane Ph3PNC(O)Ph

  Using different organomercury substrates, two isomeric cycloaurated complexes derived from the stabilised iminophosphorane Ph3P=NC(O)Ph were prepared. Reaction of Ph3P=NC(O)Ph with PhCH2Mn(CO)(5) gave the manganated precursor (CO)(4)Mn(2-C6H4C(O)N=PPh3), metallated on the C(O)Ph substituent, which yielded the organomercury complex ClHg(2-C6H4C(O)N=PPh3) by reaction with HgCl2 in methanol. Transmetallation of the mercurated derivative with Me4N[AuCl4] gave the cycloaurated iminophosphorane AuCl2(2-C6H4C(O)N=PPh3) with an exo PPh3 substituent. The endo isomer AuCl2(2-C6H4Ph2P=NC(O)Ph) [aurated on a PPh3 ring] was obtained by an independent reaction sequence, involving reaction of the diarylmercury precursor Hg(2-C6H4P(=NC(O)Ph)Ph-2)(2) [prepared from the known compound Hg(2-C6H4PPh2)(2) and PhC(O)N-3] with Me4N[AuCl4]. Both of the isomeric iminophosphorane derivatives were structurally characterised, together with the precursors (2-HgClC6H4)C(O)N=PPh3 and (CO)(4)Mn(2-C6H4C(O)N=PPh3). The utility of P-31 NMR spectroscopy in monitoring reaction chemistry in this system is described. (C) 2009 Elsevier B.V. All rights reserved.
