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

  摘要：

  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.
