Abstract
Cationic oxygen-bonded dimethyl sulphoxide (dmso) complexes of the types [M(Ph2PCH2CH2PPh2)(dmso)2][X]2 and [M(Ph2PCH2CH2PPh2)(dmso)Cl][X], where X is a non-co-ordinating anion, have been prepared with palladium(II) and platinum(II). The bis(sulphoxide) complexes are stable in solution and in the solid state, however the sulphoxide ligand in the mono(sulphoxide) complexes is very labile. In solution [Pd(Ph2PCH2CH2PPh2)-(dmso)Cl][X] readily forms the corresponding thioether (SMe2) complex by loss of oxygen from the dimethyl sulphoxide.Keywords
