[0032] Catalyst preparation
[0033] Preparation method of the present invention can be further embodied as follows with the preparation process of representative compound:
[0034] method one
[0035] [The preparation of catalyst 8 is an example]
Embodiment 1
[0036] Example 1: Catalyst 8
[0037]
[0038] General method (method 1): under the protection of argon, 50mg (0.24mmol) RuCl 3 with 300mg (1.14mmol) PPh 3 Put it into a reaction tube and install a reflux device. Add 12 mL of anhydrous CH 3 OH, heated to reflux for 5 hours. At this time, a brownish-red solid precipitated, filtered under the protection of argon, washed the solid with anhydrous ether, dried the solvent under reduced pressure, and was directly used in the next reaction.
[0039] Under argon protection, put 153 mg (0.16 mmol) of the above powdered solid into a reaction tube, add 2 mL of anhydrous THF, add 140 μL of dry triethylamine and 26 mg (0.16 mmol) of dinitrogen ligand (S)-7, and stir at room temperature After reacting overnight, white insoluble matter precipitated out. Filtrate under Ar atmosphere, drain the filtrate to about 0.5 mL, add 6 mL of anhydrous diethyl ether, a brownish-yellow solid can be precipitated, filter under argon protection, th...
Embodiment 2
[0040] Example 2: Catalyst 9
[0041] Using Method 1, the yield: 76%.
[0042] 31 P NMR (121MHz, CDCl 3 ): δ 44.62 (d, J = 38.2 Hz), 42.80 (d, J = 38.2 Hz), 36.9 (d, J = 11.0 Hz) ppm.
