NHC?Au(i) complexes bearing trispyrazolyl borate (Tp) ligands: efficient platforms for bimetallic species. Dalton Trans., 49 (2020) 6199-6204.DOI: 10.1039/D0DT00908C


Abstract


Treatment of NHC?AuCl (NHC = IPr and IMes) complexes with equimolar amounts of KTpR2 (R = Me, H) salts in tetrahydrofuran produces in high yields the heteroleptic complexes 3?6 with the general formula NHC?Au?TpR2. As the TpR ligand in complexes 3?6 features a k1-N type coordination toward the gold(I) center, the subsequent addition of group 10 and 11 metal precursors (NiII, PtII, CuII) results in the isolation of heterobimetallic Au/M complexes supported by TpR platforms. All new metal complexes have been fully characterized by elemental analysis and NMR spectroscopy, and in the case of 3, 4 and 6 by X-ray crystallography.
