Abstract

The electrochemical oxidation of trans-Rh₂(μ-dppm)₂(CO)₂Cl₂ (dppm = bis (diphenylphosphino)methane) in the presence of chloride has afforded the new dirhodium(II) unsymmetrical complex Rh₂(μ-dppm)₂(μ-Cl)(CO)Cl₃ which is readily converted to the complex [Rh₂(μ-dppm)₂(μ-Co)(μ-Cl)Cl₂]PF₆. This species has been shown to undergo addition reactions with chloride to regenerate [Rh₂(μ-dppm)₂(μ-Cl)Cl₃(CO)], and with carbon monoxide and t-butylisocyanide to give the additional new dirhodium(II) complexes [Rh₂(μ-dppm)₂(μ-Cl)Cl₂(CO)₂]PF₆ and [Rh₂(μ-dppm)₂(μ-Cl)(CNC(CH₃)₃)₂Cl₂]PF₆, respectively. During prolonged exposure to carbon monoxide [Rh₂(μ-dppm)₂(μ-Co)(μ-Cl)Cl₂]PF₆ undergoes reduction with the loss of chloride to give [Rh₂(μ-dppm)₂(μ-Cl)(CO)₂]PF₆.
