The tris(phosphine) complexes (L=CO, CN^tBu, CNC6H3Me2-2,6) react with iminooxosulphuranes, RN=S=O, (R=C6H4Me-2, C6H4Me-4) by a displacement of one labile phosphine ligand to provide .Spectroscopic data indicate that the heterocumulenes are bound to ruthenium through both nitrogen and sulphur.Sulphur dioxide coordinates in a similar bidentate mode, through sulphur and oxygen, in the complexes that are obtained upon treatment of the corresponding tris(phosphine) precursors with gaseous sulphur dioxide.
