• Synthesis and reactivity of arylgold(III) complexes from aromatic hydrocarbons via C–H bond activation

  The reactions of anhydrous gold(III) chloride [AuCl3]2 with aromatic hydrocarbons (ArH) such as benzene, toluene, xylenes, mesitylene, cumene, methoxybenzene and chlorobenzene, and the following treatment with 2,6-lutidine (lut) gave stable arylgold(III) complexes [AuArCl2(lut)]. These auration reactions proceeded heterogeneously in hexane and homogeneously in diethyl ether. The 1H NMR spectra of the arylgold(III) complexes revealed that aurations towards aromatic compounds take place regiospecifically at the position with higher electron density and with less steric hindrances. The trans configuration of the arylgold(III) complexes was established by means of their far-IR spectra and confirmed for [Au(2,5-Me2C6H3)Cl2(lut)] by its single-crystal X-ray structure. The reactions of [AuArCl2(lut)] (Ar = phenyl, 2,5-xylyl) with a terminal alkyne, phenyacetylene (HCCPh), afforded arylated phenylacetylenes ArCCPh.

  无水氯化金（III）[AuCl3]2 与芳香烃（ArH）（如苯、甲苯、二甲苯、间二甲苯、积烯、甲氧基苯和氯苯）反应，然后用 2,6 - 丁烷（lut）处理，可得到稳定的芳基金（III）络合物[AuArCl2(lut)]。这些化合反应在正己烷中异质进行，在二乙醚中均质进行。芳基金（III）络合物的 1H NMR 光谱显示，对芳香族化合物的化合反应是在电子密度较高、立体阻碍较小的位置发生的。通过远红外光谱确定了芳基金（III）配合物的反式构型，并通过单晶 X 射线结构证实了[Au(2,5-Me2C6H3)Cl2(lut)]的反式构型。AuArCl2(lut)] (Ar = phenyl, 2,5-xylyl) 与末端炔烃苯乙炔 (HCCPh) 反应生成了芳基化苯乙炔 ArCCPh。

  The reaction of CS2 with gold(III) chloride (Au2Cl6) leads to the complex AuCl2(η2-S2CCl), in which the CS2 has inserted into an Au–Cl bond of a hypothetical monomeric gold(III) trichloride intermediate; the structure has been confirmed by X-ray crystallography, although the S and CI atoms could not be distinguished.

• Vaporization and vapor complexation in the gold(III) chloride-aluminum(III) chloride system

  The vapors over solid gold(III) chloride and the vapor-phase equilibria of the gold(III) chloride-aluminum(III) chloride binary system have been investigated spectrophotometrically. The thermodynamic functions of the sublimation 2AuCl3(s) = Au2Cl6(g) were determined: DELTA-H(S)-degrees = 114.2 +/- 1.8 kJ mol and DELTA-S(S)-degrees = 160.5 +/- 3.3 J mol-1 K-1 (480 < T < 580K). One predominant vapor complex found in the binary system formed according to the reaction AuCl3(s) + 1/2Al2Cl6(g) = AuAlCl6(g) with DELTA-H(R)-degrees = 59.9 +/- 0.8 kJ mol-1 and DELTA-S(R)-degrees = 91.5 +/- 1.6 J mol-1 K-1 (470 < T < 550 K). At 470 K and 1 atm Al2Cl6(g) pressure the volatility enhancement of AuCl3 is approximately 300. The electronic absorption spectra of the Au2Cl6(g) and AuAlC16(g) molecules were interpreted in terms of a distorted square planar geometry of Au(III). "Bridged" and "terminal" ligand-to-metal charge-transfer bands were indentified in the spectra.

• Gold(III) derivatives with C(4)-aurated 1-phenylpyrazole

  The reaction of 1-phenylpyrazole (HL), with gold(III) chloride has been studied. Besides a 1:1 adduct [Au(HL)Cl-3] 1, where the ligand is bonded through the nitrogen atom, several C(4) aurated species have been isolated. Thus treatment of [AuCl3](2) with HL in dichloromethane solution affords a complex, [Au(L)Cl2HCI](n), 2, where the gold atom is bonded to the 4-carbon atom of the pyrazole ligand. Deprotonation of complex 2 by means of the not coordinating base 1,8-bis(dimethylamino)naphthalene (proton sponge), B, affords the salt [BH][Au(L)Cl-3], 3, whereas reaction of 2 with 3,5-Me(2)py and PPh3 (molar ratio 1:2) gives the neutral species trans-[Au(L)(3,5-Me(2)py)Cl-2, 4, and cis-[Au(L)(PPh3)Cl-2] 5, respectively. The structure of compound 4 solved by X-ray diffraction, unambiguously shows the anionic ligand L bonded to the gold ion through the C4 atom. Alternatively, compounds 4 and 5 can be obtained in two steps, i.e. deprotonation of 2 with NaOH to give [Au(L)Cl-2](n) 6, and reaction of 6 with 3,5-Me(2)py and PPh3, respectively. The new species were characterized by elemental analyses, conductivity measurements, IR, NMR and FAB-MS spectroscopy. (C) 1998 Elsevier Science S.A. All rights reserved.
