, p. 39 - 40 (1994)
The structure of the title compound displays the same trans effects and slight distortions from planarity as previously reported trihalide(trialkylphosphine)gold(III) structures.

This work is focused on the synthesis, characterization, and preliminary biological evaluation of bio-conjugated AuIII and CuII complexes with the aim of overcoming the well-known side effects of chemotherapy by improving the selective accumulation of an anticancer metal payload in malignant cells. For this purpose, carbohydrates were chosen as targeting agents, exploiting the Warburg effect that accounts for the overexpression of glucose-transporter proteins (in particular GLUTs) in the phospholipid bilayer of most neoplastic cells. We linked the dithiocarbamato moiety to the C1 position of three different monosaccharides: d-glucose, d-galactose, and d-mannose. Altogether, six complexes with a 1:2 metal-to-ligand stoichiometry were synthesized and in vitro tested as anticancer agents. One of them showed high cytotoxic activity toward the HCT116 colorectal human carcinoma cell line, paving the way to future in vivo studies aimed at evaluating the role of carbohydrates in the selective delivery of whole molecules into cancerous cells.

Different inorganic and organometallic gold(III) and gold(I) complexes have been tested in the addition of water and methanol to terminal alkynes. Anionic and neutral organometallic gold(III) compounds can efficiently mediate these reactions in neutral media in refluxing methanol. The compounds are added in catalytic amounts (1.6-4.5 mol% with respect to the alkyne), Thus, compounds of the general formula Q[AuRCl3], Q[AuR2Cl2], [AuRCl2]2, and [AuR2Cl]2, (Q = BzPPh3+, PPN: N(PPh3)2+ or N(Bu)4+; R = C6F5 or 2,4,6-(CH3)3C6H2) seem to behave as Lewis acids in nucleophilic additions to triple bonds. Some intermediates could be detected in the stoichiometric reaction between [Au(C6F 5)2Cl]2 and phenylacetylene that was followed by variable temperature 1H, 19F{1H}, COSY 19F{1H}-19F{1H}, and 2H{1H} NMR experiments. Compound [Au(C6F 5)2Cl]2 is also able to catalyze the hydration of phenylacetylene at room temperature. A plausible mechanism for the hydration reaction has been proposed.
