The reaction of RuCOD(dppm)/sub 2/ (COD = cis,cis-1,5-cyclooctadiene, dppm = bis(diphenylphosphino)methane) with (RhCl(CO)/sub 2/)/sub 2/ affords Ru(CO)(COD)(dppm) and (RhCl(CO)dppm)/sub 2/ at room temperature after ligand exchange. At 80/sup 0/C two further products are obtained, Rh/sub 2/Cl/sub 2/CO(dppm)/sub 2/ and RuRhCl(CO)/sub 3/(dppm)/sub 2/. A mechanism is proposed. Full spectroscopic characterization of the new complexes is described, viz., /sup 1/H, /sup 13/C, and /sup 31/P NMR and determination of the /sup 103/Rh resonance frequency. The crystal structures of RuHCl(dppm)/sub 2/ x 1/2PhMe and of RuRhH(Ph)(ThPCH/sub 2/PPh/sub 2/)(dppm)(COD) are described.
