Embodiment 1

[0263] The synthesis of embodiment 1 ruthenium complex 4a

[0264] A 50mL two-neck flask was replaced with argon, and then added ligand 3a (10mmol), CuCl (30mmol, 3eq) and 30mL of dry DCM in sequence, and then replaced with argon three times, and then protected the closed system with an argon balloon. Ruthenium complex 1b (12 mmol) was added under the protection of argon, and reacted at room temperature for 0.5 hours. After the reaction was completed, silica gel was added to the filtrate to make sand, and the crude product was obtained by silica gel column chromatography, and then washed with methanol or pentane-DCM to obtain the green solid product 4a, the yield: 32%.

[0265] After detection, the ruthenium complex (4a) 1 HNMR (400MHz, CDCl 3 ): δ18.68 (s, Ru=CH), 7.23-6.65 (m, 10H, aromatic H), 6.36 (dd, J=2.8, 9.6Hz, 1H, aromatic H), 6.03 (d, J=12.8Hz , 1H, NCH 2 ), 4.14-3.90 (m, 4H, NCH 2 CH 2 N), 3.85(s, 3H, OCH 3 ), 3.47 (d, J=12.8Hz, 1H, NCH 2 ), 2.89-1.62 (m, 1...
