Treating [IrCl(CO)(PPh3)2] with ClC(S)OR (R = C6H4Me-4) provides [IrCl2C(S)OR}(CO)(PPh3)2], which reacts with NaBH4 to give [IrHClC(S)OR}(CO)(PPh3)2]. The aryloxide group is cleaved by HCl to give [IrHCl2(CS)(PPh3)2], which is dehydrochlorinated by DBU to provide [IrCl(CS)(PPh3)2] (overall yield for “Ir(CO)” → “Ir(CS)” 75%). Treating [IrCl(CS)(PPh3)2] with ClC(S)SPh provides [IrCl2C(S)SPh}(CS)(PPh3)2]
