  The reaction of the imidazolyl-4(5)-phosphane ligands 2-isopropylimidazol-4(5)yl-diphenylphosphane (4-MIPiPr) and tris(2-isopropylimidazol-4(5)yl)phosphane (4-TIPiPr) towards gold(I) has been explored and compared to those of analogous 1-methylimidazol-2-ylphosphane ligands. The structure of [(4-MIPiPr)AuCl] (4) shows a linear P–Au–Cl coordination, whereas the 4-TIPiPr ligand forms a dinuclear complex [(4-TIPiPr)Au}2]Cl2 (5). Here, 4-TIPiPr bridges two gold(I) atoms in a head-to-tail P,N fashion. Complex 5 forms in the presence of the hard Lewis acid ZnCl2 the bimetallic complex [AuCl(4-TIPiPr)ZnCl]Cl (6), in which 4-TIPiPr bridges the two metal centers. In accordance with the HSAB concept the Au(I) atom is coordinated by the P atom and the zinc(II) by three N atoms in a N,N,N fashion. The solid-state structures of the complexes 4–6 have been elucidated by single-crystal X-ray analysis. The Au(I)–Au(I) contact in 5 is 2.8821(15) Å. The biological activities of all imidazol-2-yl- and imidazol-4(5)-ylphosphane gold(I) complexes towards nine human cancer cell lines including seven ovarian cancer cell lines of different sensitivity towards cisplatin and two leukemia cell lines have been explored.

• Gold(I) Catalysts with Bifunctional P, N Ligands

  A series of phosphanes with imidazolyl substituents were prepared as hemilabile PN ligands. The corresponding gold(I) complexes were tested as bifunctional catalysts in the Markovnikov hydration of 1-octyne, as well as in the synthesis of propargylamines by the three component coupling reaction of piperidine, benzaldehyde, and phenylacetylene. While the activity in the hydration of 1-octyne was low, the complexes are potent catalysts for the three component coupling reaction. In homogeneous solution the conversions to the respective propargylamine were considerably higher than under aqueous biphasic conditions. The connectivity of the imidazolyl substituents to the phosphorus atom, their substitution pattern, as well as the number of heteroaromatic substituents have pronounced effects on the catalytic activity of the corresponding gold(I) complexes. Furthermore, formation of polymetallic species with Au-2, Au-3, and Au-4 units has been observed and the solid-state structures of the compounds [(5)(2)Au3Cl2]Cl and [(3c)(2)Au4Cl2]Cl-2 (3c = tris(2-isopropylimidazol-4(5)-yl phosphane, 5 = 2-tert-butylimidazol-4(5)-yldiphenyl phosphane) were determined. The gold(I) complexes of imidazol-2-yl phosphane ligands proved to be a novel source for bis(NHC)gold(I) complexes (NHC = N-heterocyclic carbene).
