Abstract

Reaction of the complex [Ru2(CO)4(µ-CO)(µ-dppm)2] 1 (dppm = Ph2PCH2PPh2) with sulfur or selenium gave the corresponding [Ru2(CO)4(µ-E)(µ-dppm)2] (E = 2 or 3) in high yield. Both 2 and 3 reacted with an excess of sulfur to give the disulfido, µ-sulfido complex [Ru2(CO)2(µ-CO)(µ-S)(S2)(µ-dppm)2] 4. Complex 1 reacted readily with SO2 to give [Ru2(CO)4(µ-SO2)(µ-dppm)2] 5, containing a bridging S-bonded SO2 ligand. The complexes 1, 4 and 5 have been characterized by crystal structure determinations and are shown to contain Ru–Ru single bonds.
