Alkylation reactions of the nucleophilic platinum(II) sulfide complex [Pt-2(mu- S)(2)(PPh3)(4)] with functionalised alkylating agents have been investigated as a versatile synthetic route to dinuclear, cationic sulfide-thiolate complexes of the type [Pt-2(mu-S)(mu-SR)(PPh3)(4)](+), extending the range of thiolate complexes that can be prepared using this methodology. A wide range of functional groups can be incorporated, using appropriate alkylating agents, and include ketone, ester, amide, hydrazone, semicarbazone, thiosemicarbazone, oxime, guanidine, urea and thiourea groups.
