Abstract

The reaction of [RhCl(CS)(PPh₃)₂] with excess catecholborane affords the cumulenic carbido complex [Rh₂(μ-C)Cl₂(PPh₃)₄] which undergoes phosphine and halide substitution to afford a range of complexes in which the RhCRh spine remains intact. Amongst these, the reactions with K[L] (L = H₂B(pz)₂, H₂B(pzMe₂)₂, HB(pz)₃; pz = pyrazol-1-yl) afford [Rh₂(μ-C)(PPh₃)₂(L)₂] whilst with K[HB(pzMe₂)₃] the unsymmetrical complex [Rh₂H(μ-C)(μ-C₆H₄PPh₂-2){HB(pzMe₂)₃}₂] is obtained in which the carbido ligand spans d⁶-Rh(iii) and d⁸-Rh(i) centres.
