1,2-closo-C2B10H12 (0.400 g, 2.77 mmol) was dissolved in degassed THF (35 mL). Na metal (0.300 g, 13.04 mmol) and naphthalene (ca. 15 mg) were added and the solution stirred overnight. The resulting dark green solution was transferred via a gas-tight syringe into a second Schlenk tube containing [RuCl2(COD)]x (0.650 g, 2.32 mmol) and a large excess of naphthalene. The resulting brown mixture was heated at reflux for 90 min then allowed to cool to room temperature. The brown mixture was filtered through a short silica column eluting with DCM to afford a brown solution, removal of solvent from which yielded a brown solid. This was further purified by column chromatography (1:2 DCM:40-60 petroleum ether), giving a yellow band, followed by preparative TLC (4:3 DCM:40-60 petroleum ether, Rf 0.55) yielding, as major product C12H20B10Ru requires C 38.59, H 5.40.

0.25 g of metal sodium was mixed with well dried tetrahydrofuran in a 100 ml flask whose inside had been substituted by nitrogen and cooled to -78 C. A solution of 1.3 g of trimethylsilyl cyclopentadiene dissolved in 30 ml of tetrahydrofuran was added dropwise to the above solution in a stream of nitrogen over 1 hour and heated to room temperature under agitation over 3 hours to obtain a tetrahydrofuran solution of trimethylsilyl cyclopentadienyl sodium. Separately, 18 ml of a tetrahydrofuran solution (2.0 mol/l) of cyclopentadienyl sodium was prepared. Further separately, 5 g of dichloro(1,5-cyclooctadienyl)ruthenium was dissolved in 200 ml of well dried tetrahydrofuran in a 500 ml flask whose inside had been substituted by nitrogen. This solution was cooled to -78 C., and the above tetrahydrofuran solution of trimethylsilyl cyclopentadienyl sodium and the above tetrahydrofuran solution of cyclopentadienyl sodium were added dropwise to the solution at the same time in a stream of nitrogen over 1 hour. The resulting solution was stirred at -78 C. for 3 hours and heated to room temperature under agitation over 12 hours. After the resulting solution was let pass through a neutral alumina column in an argon gas atmosphere to be purified and concentrated, it was separated and purified by a neutral alumina column again to obtain 0.23 g of trimethylsilyl cyclopentadienyl(cyclopentadienyl)ruthenium (yield rate of 4.3%).
