Abstract
The tris(phosphine) complexes [Ru(CO)(PPh3)3(L)] (L = CO, CNtBu, CNC6H3Me2-2,6) react with iminooxosulphuranes. RNSO, (R = C6H4Me-2, C6H4Me-4) by a displacement of one labile phosphine ligand to provide [Ru(CO)(PPh3)2(L)(OSNR)]. 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 [Ru(CO)(PPh3)2(L)(SO2)] that are obtained upon treatment of the corresponding tris(phosphine) precursors with gaseous sulphur dioxide.
