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).
