Halogenation of A-frame μ-carbido complexes: a diamagnetic rhodium(ii) carbido complex†
Abstract
The reaction of [Rh2(μ-C)Cl2(PPh3)4] with 1,1′-bis(diphenylphosphino)ferrocene (dppf) affords the μ-carbido complex [Rh2(μ-C)Cl2(μ-dppf)2] which reacts with PhICl2 to provide a diamagnetic dirhodium(II) carbido complex [Rh2(μ-C)Cl4(μ-dppf)2].
