| 72% | In tetrahydrofuran; at 20℃; for 2h;Inert atmosphere; | General procedure: A 50-mL round-bottom flask was charged with [Ru(p-cymene)Cl2]2 (0.2029 g, 0.331 mmol) and CH2Cl2(20 mL). To the orange solution was added P(C6H4F)3 (0.2199 g, 0.695 mmol), and the mixture was leftto stir for 3 h at room temperature. The volatiles were removed in vacuo to leave a dark red oil, andhexanes were added to precipitate a solid product. The resulting orange solid was collected by vacuumfiltration and dried in vacuo (0.3529 g, 86percent yield). |

| {RuCl(p-cymene)}2(50 mg, 0.08 mmol) and DiPy-G1-MEH (276 mg, 0.16 mmol) were dissolved in distilled DMF (25 mL). The reaction mixture was heated at 80 C. under nitrogen for 4 hours. Then, 2,2'-bipyridine-4,4'-dicarboxaldehyde (Dcbpy) (40 mg, 0.16 mmol) was added and refluxed at 150-160 degrees C. for another 4 hours under reduced light to avoid isomerization (2,2'-bipyridine-4,4'-dicarboxaldehyde was prepared according to the method described in N. Garelli et al, J. Org. Chem. 1992, 57, 3046). Subsequently, an excess of NH4NCS (310 mg, 4.1 mmol) was added to the mixture and heated at 150 C. for a further 4 h. The reaction mixture was cooled to room temperature and the solvent was removed by using a raotary evaporator under vacuum. Water (20 mL) was added to the flask and the insoluble solid was collected on a sintered glass crucible by suction filtration, and washed with distilled water. The crude complex was dissolved on a solution of tetrabutylammonium hydroxide (TBAH) in methanol (5 mL). the concentrated solution was charged onto a Sephadex LH-20 column and eluted with methanol. The main band was collected and concentrated. The required complex was isolated upon addition of 0.01M HNO3. |

Solvent was removed under reduced pressure until an orange oil was obtained. With the addition of diethyl ether an orange precipitate was obtained, which was filtered off, washed with diethyl ether and dried under reduced pressure.

| 95% | In methanol; at 20℃; for 0.5h; | General procedure: Dichlorop-cymene Ruthenium (II) dimer (2) (50 mg, 0.08 mmol) was dissolved in5 ml of methanol in 50 mL RB flask placed on a magnetic stirrer followed by0.17 mmol (1:2.1 mole ratio) of 8-Hydroxy Quinoline derivatives (1a-e) was added to reaction mixture andthen stirred continuously for 30 minute at ambient temperature, color changewas observed from deep yellow to deep orange. Progress of this chemicalreaction was monitored by thin layer chromatography in ethyl acetate. Aftercompletion of the reaction, solvent methanol was evaporated by using rotatorevaporator.

| 60% | A mixture of [Ru(p-cymene)Cl2]2 (102.7 mg, 0.16 mmol) and H2-dcbpy (81.3 mg, 0.33 mmol) were heated under N2 in dry DMF (20 ml) at 60 C overnight. 4,4'-F2-bpy (63.7 mg, 0.33 mmol) was added and the temperature increased to 140 C for 2 h. Excess NH4NCS (1.0073 g, 13.23 mol, 40 times excess) was then added and heating continued at 140 C for 3 h. After allowing to cool, the solvent was then removed using reduced pressure and the resulting black solid stirred in water overnight to remove any unreacted NH4NCS. Upon filtering the crude product was formed as a darkred/brown solid. Purification was achieved by dissolving the crude product in NaOH solution (0.1 M, in methanol) and performing Sephadex column chromatography using methanol as the eluent. This produced the pure product 1 (69.8 mg, 0.10 mmol, 60% yield)as a dark red solid. 1H NMR (600 MHz, CD3OD) delta (ppm): 9.54 (d,J = 5.7 Hz, 1H), 8.93 (s, 1H), 8.85 (d, J = 6.7 Hz, 1H), 8.78 (s, 1H),8.15 (dd, J = 5.6 Hz, 1.6 Hz, 1H), 7.76 (d, J = 6.0 Hz), 7.53 (dd,J = 5.9 Hz, 1.6 Hz, 1H), 7.52 (s, 1H), 7.40 (s, 1H), 7.01 (dd,J = 6.60 Hz, 2.47 Hz, 1H), 6.85 (d, J = 6.9 Hz, 1H), 6.32 (dd,J = 6.7 Hz, 2.6 Hz, 1H).

| In methanol; at 20℃; for 3h; | General procedure: [Ru(mu-Cl)(eta6-p-cym)Cl]2 (0.1 mmol, 61.2 mg) was dissolved in methanol (5 mL) and left toreact with two molar equivalents of the corresponding naza. The reaction mixture was stirredat ambient temperature for 20 min (reactions with 5Braza and 5Faza), 2 h (reactions with aza,3Iaza and 3Claza) or 3 h (reactions with 2Me4Claza, 3Cl5Braza and 3I5Braza), until the yellow(for 2, 4 and 5), or light (for 8) or dark (for 1, 3, 6 and 7) orange product was formed. Theproducts (Fig 1) were isolated by filtration, washed with methanol (2 × 2 mL) and diethyl ether(3 × 5 mL) and dried under the infrared lamp (40C, 4 h). The yields were 60-80%. |

| 60% | With potassium acetate; In dichloromethane; at 20℃; for 20h;Inert atmosphere; Schlenk technique; | Dichloromethane (10 mL) was added to dichloro(pcymene)ruthenium(II) dimer (0.16 mmol) in a round bottom flask. To this solution were added, L6 (0.33 mmol) followed by potassium acetate(0.38 mmol). The reaction mixturewas stirred at room temperature for 20 h. Then the solvent was evaporated and the residue leftbehind was dissolved in dichloromethane and the mixture wasfiltered. The filtratewas then added to large volume of diethyl etherresulting in a precipitate which was filtered and washed withdiethyl ether and dried.
