Oxo-bridged gold(III) complexes are useful precursors to synthesize organogold complexes, which have importance as intermediates in homogeneous catalysis. The synthesis of complexes of the type [Au2L2(µ-O)2](BF4)2 is explored starting from [AuLCl2]BF4 and reacting with either KOH or Ag2O in aqueous solution. Different bidentate ligands L are employed: phenanthroline, 1,2-bis(diphenylphosphino)benzene (dipohs), and 1,2-bis(phenylthio)benzene. With these ligands structure-reactivity relationships will be investigated. In case of the synthesis of complex [AuLCl2]BF4 (L = diphos) by reaction of Na[AuCl4] and diphos, one of the products was analyzed as two-coordinate gold(I) complex where one of the phosphorus of the diphos ligand is oxidized. The X-ray crystal strycture analysis of this structure will be reported.
