[Ru2(OOCCH3)4(THF)2]BF4 (SBU-c)<br />

The compound was synthesized under Ar using the method reported in the literature. [200]<br />

SBU-a (100 mg, 0.211 mmol) and AgBF4 (42 mg, 0.211 mmol) were stirred in dry THF (4<br />

ml) with the protection of tin foil at room temperature. A red solution and white<br />

precipitate of AgCl was obtained after 24 h. The solution was filtered and the precipitate<br />

was washed several times with THF until colorless. All the filtrates were collected<br />

together, and the volume was reduced (ca. 4 times) in vacuum and the product was<br />

obtained (Yield: 108 mg).<br />
