Sulfur(IV) Compounds as Ligands, IX. - Binuclear Molybdenum-Rhodium Complexes with Sulfur Dioxide as a Bridging Ligand

The hetero-binuclear complexes 1CH2E3Ph2)(μ-Ph2E2CH2E4Ph2)> (E = P, As, 1-4), (5) and MoRh(CN)(CO)3(μ-SO2)(μ-Ph2PCH2PPh2)2> (6) are the first compounds which contain sulfur dioxide as a bridging ligand connected to two metal atoms from different groups of the periodic table.The synthesis starts from Mo(CO)3(NCMe)3 (7), which reacts with the chelating ligands Ph2PCH2PPh2 (dppm), Ph2AsCH2PPh2 (dapm), and Ph2AsCH2AsPh2 (daam) to give the mononuclear precursors Mo(CO)3(ν2-Ph2E1CH2E3Ph2)(ν1-Ph2E2CH2E4Ph2) (9-12).With these are converted to the binuclear complexes 1CH2E3Ph2)(μ-Ph2E2CH2E4Ph2)> (15-18).Reversible CO/SO2 exchange finally gives 1-4 and the analogous bromide 5, the cyanide complex 6 is obtained from 1 and NaCN in liquid ammonia. - Key Words: Binuclear complexes/ Molybdenum Complexes/ Rhodium Complexes/ Sulfur dioxide bridges
