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.

11 g of trimethylsilyl chloride was dissolved in 30 mol of well dried tetrahydrofuran in a 300 ml flask whose inside had been substituted by nitrogen, and the obtained solution was cooled to -78 C. 100 ml of a tetrahydrofuran solution (2.0 mol/l) of cyclopentadienyl sodium was added dropwise to the above solution in a stream of nitrogen over 1 hour. The solution was stirred at -78 C. for 1 hour and returned to room temperature over 6 hours. A salt precipitated in the mixture solution was removed by filtration in a nitrogen atmosphere, and the residual solution was distilled to obtain 8 g of trimethylsilyl cyclopentadiene. 0.5 g of metal sodium was mixed with a well dried tetrahydrofuran solution in a 300 ml flask whose inside had been substituted by nitrogen, and the resulting solution was cooled to -78 C. A solution of 2.5 g of the above synthesized trimethylsilyl cyclopentadiene dissolved in 30 ml of tetrahydrofuran was added dropwise to the above solution in a stream of nitrogen over 1 hour and further heated to room temperature under agitation for 3 hours to obtain a tetrahydrofuran solution of trimethylsilyl cyclopentadienyl sodium. Separately, 5 g of dichloro(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 synthesized tetrahydrofuran solution of trimethylsilyl cyclopentadienyl sodium was added dropwise to the above solution in a stream of nitrogen over 1 hour.
