Thermolysis of Ru3(CO)12 in the presence of 4,5-bis(dimethylsilyl)-9,9-dimethylxanthene (xantsilH2) (1) at 120°C afforded cis-Ru(CO)4(xantsil) [2; xantsil = (9,9-dimethylxanthene-4,5-diyl)bis(dimethylsilyl)] as a main product. Isolated 2 reacted with toluene on reflux to give cis-Ru(CO)(xantsil)(η6-C6H5CH3) (3). The η6-toluene ligand of 3 was cleanly replaced with η6-benzene at room temperature by simply dissolving 3 in benzene.
