The synthesis of two organogold(i) complexes, [(Au(NCN)) 2(dppbp)] (6) and [(Au(Phebox))2(dppbp)] (9), and their application in subsequent transmetalating reactions are described. A trinuclear organogold(i) complex, [(AuCl)3(tdpppb)] (4) is also reported, which exhibits a surprisingly high solubility in dichloromethane. It was found that 6 and 9 can cleanly transfer the anionic NCN-([C6H3(CH 2NMe2)2-2,6]-) or Phebox-([2,6-bis(oxazolinyl)phenyl]-) moiety to TiIV and PdII centers, respectively. The coproduct [(AuCl)2(dppbp)] (3, dppbp is [4-Ph2PC6H4]2 (1)) formed during this transmetalation reaction, precipitates almost quantitatively from the reaction mixture (toluene) and can thus be separated by simple filtration. In comparison, [AuCl(PPh3)], formed as the coproduct in the transmetalation reaction of [Au(NCN)(PPh3)] with metal salts, has a higher solubility in apolar solvents and thus is more difficult to separate from the resultant organometallic complex. Digold complex 6 has been characterized by NMR spectroscopy and crystallographic analyses. These analyses show that the two gold units are essentially independent. The formation of a dimetallic transmetalating agent based on gold(i) had no effect on its transmetalating properties. The Royal Society of Chemistry 2007.
