Embodiment 1
[0074] Embodiment 1: the synthesis of compound 1
[0075]
[0076] (1) Under a nitrogen atmosphere, S-1 (10 mmol) and S-2 (11 mmol) were completely dissolved in tetrahydrofuran / water (2:1, 80 ml) in a round bottom flask, and potassium carbonate ( 5 g), tetrakis(triphenylphosphine) palladium acetate (0.1 g), and the mixture was heated to reflux for 10-12 hours. After cooling down to room temperature, add acetic acid (2 ml) and stir for 1 hour, separate the upper tetrahydrofuran layer, filter it with diatomaceous earth, concentrate the solvent in vacuo, and use petroleum ether:ethyl acetate (20:1~2:1) as The eluent was purified and separated on a silica gel column to obtain S-3 (yield 83%), LC-MS, 655.3.
[0077] (2) Under nitrogen atmosphere, put S-1 (10 mmol), K 2 PtCl 4 (10 mmol), acetic acid (8 ml), heated to reflux for 3 days. After cooling down to room temperature, a yellow solid was obtained by filtration, and purified and separated on a silica gel column with petr...

[0078] Embodiment 2: the synthesis of compound 2
[0079]
[0080] The synthesis steps of compound 2 are similar to those of compound 1, and the yield of the final metal complex is 78%. LC-MS: theoretically 1036.43, measured: 1036.4; elemental analysis C: 68.32; H: 5.73; N: 4.05; measured: C :68.34; H:5.77; N:4.07.
Embodiment 3
[0081] Embodiment 3: the synthesis of compound 3
[0082]
