The reagent has been prepared, and used to synthesise several mixed-metal complexes in which gold atoms are bonded to rhodium.Thus treatment of the gold salt with trans- or in thf (tetrahydrofuran), in the presence of TlBF4, affords the complexes 5-7,8-C2B9H9Me2)> (L = PPh3 or CO), respectively.Reaction of the gold species with gives the complex , the structure of which has been established by X-ray diffraction.The latter complex in solution exists in equilibrium with a minor isomer 5-7,8-C2B9H9Me2)> containing a closo-3,1,2-RhC2B9 cage system.With the rhodium complex (cod = cycloocta-1,5-diene), and in the presence of molecular hydrogen, the gold reagent yields a chromatographically separable mixture of and 5-7,8-C2B9H9Me2)>.A single-crystal X-ray diffraction study has established the structure of the rhodium-digold compound.The NMR data (1H, 13C-(1H), 31P-(1H) and 11B-(1H)) for the new compounds are reported and discussed in relation to their structures.
