Abstract

The reaction of [Rh2(μ-C)Cl2(PPh3)4] with bis(diphenylphosphino)methane (dppm) affords the A-frame μ-carbido complex [Rh2(μ-C)Cl2(μ-dppm)2], halide metathesis of which provides [Rh2(μ-C)Br2(μ-dppm)2]. The reactions of the former with PhICl2 or the latter with [pyH][Br3] provide rare examples of μ2-halocarbyne ligands in the complexes [Rh2(μ-CX)(μ-X)X4(μ-dppm)2] (X = Cl, Br).
