General procedure: The following common procedure was followed for the synthesesof complexes 1-5: A mixture of the ligand (0.36 mmol) and Ru(1,5-cod)Cl2(0.36 mmol) was dissolved in dry ethanol (10 ml) and the resultingmixture was refluxed for 2 h. The reaction volume was concentratedto a third of its original volume and the suspension was keptat 4 C overnight to give brick red solid which was filtered off,washed with cold ethanol and then diethyl ether. The solid wasdissolved in chloroform and excess of n-hexane was added toinduce the precipitation of the brick red solid product.

Na2[7,10-nido-C2B10H12] was dissolved in degassed THF (45 mL) giving a purple solution. Excess Na was removed from the reduced carborane solution to give a colourless solution which was then transferred into a Schlenk tube containing [RuCl2(COD)]x (0.780 g, 2.78 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 (2:1 DCM:40-60 petroleum ether, Rf 0.38) yielding solid. C12H20B10Ru requires C 38.59, H 5.40. Found: C 39.48, H 4.87%.

A mixture of [RuCl2(COD)]n (155 mg, 0.552 mmol) and la (147 mg, 0.552 mmol) was stirred in toluene (10 ml) at 115 C for 48 h in Kontes pressure tube. After cooling, a brick-colored precipitate was collected on a filter frit, washed with Et20 (3 x 10 ml) and vacuum dried on the filter. The material was extracted on the filter with 5 x 3 ml CH2C12 allowing the filtrates to be collected in 5 separate vials. A red solution in each vial was layered with Et20 (20 ml). In 1 week, the combined precipitates (or red crystals) from each vial were collected, washed with Et20 (3 x 10 ml) and vacuum-dried to afford 144 mg of the desired product (60%). Elem.

Found (under nitrogen): C, 38.61; H, 4.99; N, 6.17%.

The same compound is obtained if the synthesis is carried out in the presence of P(C6F5)3. (0457) [0216] An X-ray structure of complex K-1 revealed that one ligand coordinates to one Ru atom via mer-fashion. A second ligand coordinates to second Ru atom via ^ac-fashion. Both Ru atoms are connected via one bridging CI atom. One S(Ph) atom is part of mer-coordinated la. There appears to be a hydrogen-bonding interaction between one NH group of the fac- coordinated ligand and terminal CI atom attached to the first Ru atom. Complex K-1 exists as a single species in solution. The NH hydrogen atom H-bonded to the chloride ligand appears at delta 9.19 ppm in the 1H NMR spectrum. It is shifted to low field by Deltadelta = 4.47 ppm relative to the NH resonance of the non-H bonded NH group.

Separately, 200 ml of well dried tetrahydrofuran was fed to a 500 ml flask whose inside had been substituted by argon, and 5 g of dichloro(cyclooctadienyl)ruthenium was injected into the flask and well mixed with tetrahydrofuran to obtain a suspension. This suspension was cooled to -78 C. in a stream of argon, and 14 ml of a tetrahydrofuran solution of the above synthesized fluorocyclopentadienyl sodium was added dropwise to the above suspension over 1 hour. The obtained reaction mixture was further stirred at -78 C. for 3 hours and returned to room temperature under agitation over 12 hours. After the reaction mixture was let pass through a neutral alumina column in a stream of argon to be purified and concentrated, it was purified again by a neutral alumina column to obtain 0.4 g of bis(fluorocyclopentadienyl)ruthenium (yield rate of 8.4%).

The synthetic route of 50982-12-2 has been constantly updated, and we look forward to future research findings.
