Between T and Y: Asymmetry in the Interaction of LAu(I) with Bipy and beta-Diiminate-like Ligands
The combination of an LAu(I) fragment with a potentially chelating ligand L’<^>L’ can result in different coordination modes of L’<^>L’ : strictly monodentate, symmetrically bidentate, or intermediate with asymmetric bidentate binding of L’<^>L’ . Density Functional calculations indicate that for pi-acceptor ancillary ligands L (C2H4, CO) and bis(nitrogen) donors L’<^>L’ (bipyridine, phenanthroline, beta-diiminate) symmetric chelate structures are obtained. With primarily sigma-donating ancillary ligands L (Me-, Cl-, MeCN) the asymmetric coordination mode is the norm. Phosphine ancillary ligands L are on the edge and display the highest sensitivity to ligand variation. Asymmetry increases when (a) going from anionic (beta-diiminate) to neutral (bipyridine, phenanthroline) bidentates L’<^>L’ ; (b) making L’<^>L’ less electron-rich e. g. through having aryl instead of alkyl groups at N or through introduction of CF3 substituents. Inversion of the asymmetry through gold hopping is remarkably facile (barrier mostly <6 kcal/mol, often similar to 1 kcal/mol). The high-temperature fluxionality reported for two (PPh3)Au(beta-diiminate) complexes is tentatively assigned to imine inversion (rather than gold hopping) as the rate-limiting step. Synthetic Route of 73-22-3, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 73-22-3 is helpful to your research.
