Preparation and Reactivity of a Ruthenium Complex Bearing a 2,6-Bis(trimethylsilyl)benzenethiolate Ligand

The reaction of [Cp*Ru(μ3-Cl)]4 with ArSK (ArS = 2,6-(Me3Si)2C6H3S) gives the mononuclear ruthenium complex with π-arenethiolate ligand [Cp*Ru(η5-SAr)] via [Cp*Ru(μ-SAr)]2. Further reactions of [Cp*Ru(η5-SAr)] with HCl and [Cp*Ru(μ3-Cl)]4 give the corresponding monoruthenium complex [Cp*Ru(η6-HSAr)]Cl and diruthenium complex [Cp*Ru(μ-η5:η1-SAr)RuClCp*] in high yields, respectively.
