  Synthesis and Structure of a Diphosphonite-Bridged Ruthenium Dication, {[(p-cymene)Ru(μ-Cl)]₂(μ-1,2-di(2‘2‘-diethyl-1‘,3‘-propanedioxy)phosphinoethane)}²⁺

  摘要：

  Attempted synthesis of [(p-cymene)Ru(PP)](2+) (PP = 1,2-di(2'2'-diethyl-1',3'-propanedioxy)phosphinoethane) by reaction of [(p-cymene)RuCl2](2) with PP followed by chloride abstraction with AgSbF6 afforded instead the diphosphonite-bridged Ru-II dimer, {[(p-cymene)Ru(mu-Cl)](2)(mu-PP)}[SbF6](2), which was structurally characterized. A neutral intermediate, [(p-cymene)RuCl2](2)-(mu-PP), was isolated and was converted to the latter by treatment with AgSbF6.

  Trans-RuCl2(PP)(2) (2) and cis-FeCl2(PP)(2) (4) have been synthesized by the reaction of the diphosphonite 1,2-bis((2,2-diethyl-1,3-propanedioxy)phosphino)-ethane (PP) with RuCl2(Ph3P)(3) and FeCl2, respectively. Complex 4 was converted to cis-FeMe2(PP)(2) (5), for which a molecular structure was obtained.
