文摘

Aerobic oxidation of one P atom in cis-RuCl₂(P-P)(L₂) complexes (P-P = (R)-BINAP (2,2'-bis(diphenylphosphino)-1,1'-binaphthyl) or dppb (1,4-bis(diphenylphosphino)butane), L₂ =bipy (2,2'-bipyridine) or phen (1,10-phenanthroline)) generates species such as [RuCl(BINAPO)(L₂)]PF₆ and cis-RuCl₂(dppbO)(L₂) containing the corresponding bis(phosphine)monoxide ligands [BINAPO = 2-(diphenylphosphinoyl)-2'-(diphenylphosphino)-1,1'-(binaphthyl), and dppbO = 1-(diphenylphosphinoyl)-4-(diphenylphosphino)butane)]. A novel coordination mode of BINAPO, involving the P^III atom, the O atom, and an ²-naphthyl interactionproximate to the oxidized P atom, is identified by X-ray crystallography.
