  Synthesis and Reactivity of Trinuclear Gold(III) Dithiolate Complexes. X-ray Structure of [Au(C6F5)(S2C6H4)]3 and [Au(C6F5)(S2C6H4)(SC6H4SPPh3)]

  摘要：

  Q(2)[Zn(S-S)(2)] or [SnMe(2)(S-S)] (Q = NBu(4) or PPN, S-S = S2C6H4, S2C6H3CH3, or C3S5 (dmit)) reacts with trans-[Au(C6F5)Cl-2(tht)] affording trinuclear species [Au(C6F5)(S-S)](3) (1-3). When [AuX(3)(tht)] (X = Cl or Br) are used instead, [AuBr(S-S)], (4-6) and [AuCl(dmit)](n) (7) are obtained. Complex 1 further reacts with PPh(3) to give [Au(C6F5)(S2C6H4)(SC(6)H(4)SPPh(3))]. Complexes 1-3 react with neutral (pyridine) or anionic (Cl, Br, or SCN) ligands affording [Au(C6F5)(S-S)(py)] (9a-c) or Q[Au(C6F5)(S-S)X] (10a-c-12a-c) complexes. The structures of 1 and 8 have been established by X-ray crystallography. Complex 1 shows a six-membered Au3S3 ring which adopts a chair configuration and shows a gold-gold distance of 3.515 Angstrom. Complex 8 is a mononuclear square-planar gold(III) complex with a new SC(6)H(4)SPPh(3) thiolate ligand, the P-S bond length being 2.058(5) Angstrom.

  Addition of a bidentate ligand (LL = 1,10-phenanthroline, o-phenylenebis(dimethylarsine)) to solutions of Au(C6F5)X2(tht) (X = Cl, Br; tht = tetrahydrothiophene) leads to potentially five-coordinate gold(III) derivatives. 197Au Mössbauer spectroscopy points, however, to four-coordinate square-planar complexes with a weak penta-coordination in the phen-containing derivatives. The complexes react with

  anionic salts mediate the 1,3-dipolar cycloaddition of N-benzyl-C(2-pyridyl)nitrone (2-PyBN) (1) and methyl acrylate (2) (gold 5–10 mol% with respect to the nitrone) decreasing the reaction time and favouring the formation of the exo (cis) isomer. The best catalyst found was Na[AuCl4] (7) able to perform the addition reaction in 56 h (instead of the 96 h required for the control experiment) and giving
