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.

In a glove box, NHC ligand precursor 23 (63 mg, .13, mmol), ruthenium precursor 11 (78 mg, .13 mmol) and KOMJu(Fe) (29 mg, .13 mmol) were combined in toluene. The flask was sealed, removed from the glove box and stirred at 60 0C for 18 hours. The reaction was concentrated and purified by flash column chromatography (5% –> 20% Et2O/Pent). There were 3 bands that could be isolated from this column, first 2 brown bands and then one green band. The second brown band was the desired product; however, it was not completely pure after one column. Recolumning in 10% Et2O/Pentane gave a brown oil product completely pure by 1H NMR (9 mg, 9%) and another fraction still slightly impure (18 mg, 18%).

EXAMPLE 1 Synthesis of (2,4-dimethylpentadienyl) (ethylcyclo-pentadienyl) Ruthenium and Heat Decomposition Properties Thereof 400 g of zinc was weighed into a four-necked flask. After purging the container with argon, 205 ml of 2,4-dimethyl-1,3-pentadiene was added thereto to give a suspension. Then a solution of 30 g of ruthenium trichloride n-hydrate (n: about 3) dissolved in 1000 ml of methanol was dropped thereinto at room temperature over 40 minutes. After the completion of the dropping, the mixture was stirred at room temperature for 30 minutes, then heated to 60 C. and stirred for additional 2 hours. The mixture was once cooled by allowing to stand and then 12 ml of ethylcyclopentadiene was added thereto. The resultant mixture was stirred as such at room temperature for 30 minutes, then heated to 60 C. and stirred for additional 2 hours. After the completion of the reaction, the mixture was cooled to room temperature and the unreacted zinc was removed with the use of a glass filter. Next, it was extracted with hexane (750 ml*1, 300 ml*4). The extracts were concentrated under reduced pressure and the oily product thus obtained was distilled under reduced pressure to thereby give 25.4 g of target (2,4-dimethylpentadienyl) (ethylcyclo-pentadienyl) ruthenium (yield: 76.3%). Oily yellow product: 1H-NMR (500 MHz, CDCl3, deltappm) 5.38 (s, 1H), 4.63 (t, J=2.0 Hz, 2H), 4.52(t, J=2.0 Hz, 2H), 2.70 (d, J=2.5 Hz, 2H), 2.15 (q, J=7.5 Hz, 2H), 1.93 (s, 6H), 1.12 (t, J=7.5 Hz, 3H), -0.09 (d, J=2.5 Hz, 2H) IR (neat, cm-1)
