Embodiment 1
[0037] Embodiment one (X=Cl)
[0038] Weigh 0.0623gCu(PPh 3 ) 2 Dissolve Cl (0.010mol) in 3.0ml of dichloromethane to obtain a colorless solution, put it into a test tube, add 3.0ml of methanol / dichloromethane (1:1), and finally add 0.0184g of 4,4'-azopyridine (0.010mol) Red solution in 3.0 ml of methanol and the layers were allowed to separate. A few days later, a large amount of black crystals were formed. After filtration, a large amount of black blocky crystals were obtained, which were washed with anhydrous ether and dried in air. The yield was 0.0441 g, and the yield was 82%. Elemental Analysis Calc.For C 24 h 21 Cl 3 CuN 2 P (%): C 53.55, H 3.93, N 5.20. Found (%): C 53.70, 7H 3.89, N 5.15.

Embodiment 2
[0039] Embodiment two (X=Cl)
[0040] Large amount of synthesis: Weigh 0.6238gCu(PPh 3 ) 2 Cl (0.986mmol) was dissolved in 15.0ml of dichloromethane to obtain a colorless solution, and finally a red solution of 0.1843g of 4,4'-azopyridine in 15.0ml of methanol was added and stirred to obtain a red solution. A few days later, a large number of black crystals were formed. After filtration, a large number of black blocky crystals were obtained, which were washed with anhydrous ether and dried in air. The yield was 0.4512 g, and the yield was 85%.
Embodiment 3
[0041] Embodiment three (X=Br)
[0042] Weigh 0.0672gCu(PPh 3 ) 2 Dissolve Br (0.010mmol) in 3.0ml of dichloromethane to obtain a colorless solution, put it into a test tube, add 3.0ml of methanol / dichloromethane (1:1), and finally add 0.0184g of 4,4'-azopyridine (0.010mmol) Red solution in 3.0 ml of methanol and the layers were allowed to separate. A few days later, a large number of black crystals were formed. After filtration, a large number of black blocky crystals were obtained, washed with anhydrous ether, and dried in air. The yield was 0.0391 g, and the yield was 78%. Elemental Analysis Calc.forC 23 h 19 BrCuN 2 P (%): C 55.49, H 3.85, N 5.63. Found (%): C 55.34, H 3.91, N 5.27.
